article: When a young mum posted images of her post-pregnancy body on Instagram to inspire others, she might have anticipated a raft of supportive comments for her bravery. Hannah Moore, 20, from Broxburn in West Lothian, didn't get that far though; her images of the stretchmarks on her tummy were vetoed by the world's biggest photo-sharing website within minutes of her posting them. The mum-of-twins claims her account was deleted because the images were deemed to contain inappropriate 'nudity and violence' which breach the site's decency guidelines. Scroll down for video . Confidence shattered: Hannah Moore, who had shots of her stretchmarked stomach removed 'within two minutes' of posting them on photo-sharing site Instagram, said the rebuttal had taken her confidence away . Body pride: Hannah Moore, 20, of Broxburn in West Lothian, shared photos of her post-childbirth body. She gave birth to twin girls Lily and Grace (pictured above with fiance David Johnstone, 22) in June last year . Hannah suffered from stretch marks after giving birth to twin girls Lily and Grace with fiance David Johnstone, 22, in June last year. Moore said: 'Nobody could get on my Instagram and nobody could search for it so someone had obviously reported the picture for nudity - all it was was a picture of my belly and it has just took my confidence away.' It's yet another example of Instagram coming under fire for refusing to publish certain images, particularly photos that are dedicated to showing the female form in its most honest state. Shots of menstrual blood, stretchmarks following childbirth, pubic hair and naked breasts have all felt the wrath of the site's censors. Critics have also highlighted that plenty of images that many might find offensive such as users bragging about extreme wealth while poking fun at the poor or pro-guns graffiti often get the green light for publication. Just last week, Instagram, which boasts 300 million monthly users, announced that it has toughened up its rules on the types of pictures users can post in a bid to cut down on pornography and harassment. Samm Newman received an apology from Instagram for removing these images of her in her underwear. The 19-year-old had posted the shot to celebrate her curves...but later found they had been removed . Megan Tonje saw a picture of her bottom - covered by sizeable black pants - banned for contravening Instagram's rules, even though she posted it in a spirit of body confidence with the hashtags #honormycurves and #effyourbeautystandards . The overhaul of Instagram's community guidelines is the biggest since Facebook bought the app three years ago for $1 billion. Although it has banned 'close-ups of fully nude buttocks', it remains perfectly fine to post a shot of a woman's rear if she is wearing underwear. A spokesman for the site said: 'We know that there are times when people might want to share nude images that are artistic or creative in nature, but for a variety of reasons, we don’t allow nudity on Instagram. One rule for one: Images such as the shot above, taken from the picture stream of American social media star Dan Bilzerian, appear liberally on the site . Star support: Willow Smith joined the campaign to use images of bare breasts by tweeting this picture on her @officialWillow Twitter page last year . The #freethenipple campaign saw a host of web users staging their protests against what they perceived as sexism by Instagram . 'This includes photos, videos, and some digitally-created content that show sexual intercourse, genitals, and close-ups of fully-nude buttocks. 'It also includes some photos of female nipples, but photos of post-mastectomy scarring and women actively breastfeeding are allowed. 'Nudity in photos of paintings and sculptures is OK, too.' However, the boundaries laid out above seem to contradict the image posted by many. When singer-songwriter Meghan Tonje published an image of her bottom in underwear in May 2014, she was dismayed to find it promptly removed for being deemed as 'mature' content. Tonje says you don't need to wander very far on Instagram to find images of photos of other women in a similar pose, which have all been published by the site, leading to accusations that she was discriminated against because she was bigger than some of the bikini models who feature. Elsewhere, earlier this year, an Australian media agency Sticks and Stones claimed the site had removed one of its images which showed two women wearing bikinis and showing some pubic hair. Sticks and Stones said the photo-sharing site had 'censored' their image and argued that it was a sexist move and it would not have happened had the shot been a picture of two men. Ainsley Hutchence, the agency's director, said at the time: 'Unfortunately Instagram has ruled out natural hair that appears on all bodies of women that don't trim their bikini lines. 'This hair occasionally does spill out of the sides of swimwear as it does on men in their underwear. But Instagram seem to be ok with man pubes.' He added: 'Clearly this is absolutely sexist. Instagram believes that women should wax or get off their platform.' This shot, published by Australian media agency Sticks and Stones, was banned by Instagram for showing public hair. The agency said it though the image would have been published if it had shown two men . When photographer Rupi Kaur published a photo of a woman lying fully clothed on a bed with menstrual blood between her legs, the site removed it twice, saying that Kaur wasn't following 'community guidelines'.Instagram eventually apologised. Other high profile bans include a protest by Scout Willis (daughter of Bruce Willis and Demi Moore) who saw a photo of a jumper with two bare-breasted women on it removed from the site. Willis said at the time: 'Women are regularly kicked off Instagram for posting photos with any portion of the areola exposed. 'While photos sans nipple – degrading as they might be – remain unchallenged.' Such 'unchallenged' images might include the profile of US poker player Dan Bilzerian, who regularly posts near pornographic images of women alongside misogynistic language. His posts include a woman dressed in provocative school uniform-type dress but with her shirt tied beneath her breasts and  only pink tape covering her nipples. In other shots, scantily clad women cavort together or thrust their cleavage into the camera. After pressure from critics, the world's most popular photo-sharing website has been forced to clarify how it treats certain images. Last week, Instagram said it was making clearer what exactly is allowed. 'We know that there are times when people might want to share nude images that are artistic or creative in nature, but for a variety of reasons, we don’t allow nudity on Instagram. Fans were not happy when Michael Buble shared this Instagram photo from his Miami holiday accompanying it with hashtags that included the words '#myhumps #babygotback #hungryshorts' Despite stipulating that close-ups of 'fully nude buttocks' are banned on the service, Kendall Jenner posted a side-on view of her posterior without complaints . 'This includes photos, videos, and some digitally-created content that show sexual intercourse, genitals, and close-ups of fully-nude buttocks. 'It also includes some photos of female nipples, but photos of post-mastectomy scarring and women actively breastfeeding are allowed. 'Nudity in photos of paintings and sculptures is OK, too.' Its censoring filter may have received attention but as our images  show, there are plenty of photos that might cause offense that have made it through: . When global music star Michael Bublé posed in front of a female in Miami last week to deliberately highlight her bottom, the image was promptly published to his million-strong following on Instagram. The photo, which the singer tagged with the words '#myhumps #babygotback #hungryshorts #onlyinmiami', shows a close shot of Bublé in the foreground  while the rear of a female shopper was clearly in view. In spite of a public apology and wide criticism, the image remains on Bublé's site. Such 'unchallenged' images might include the photostream of US poker player Dan Bilzerian, who regularly posts images of scantily clad women. Many Instagram users will be baffled as to why an  image depicting a woman who is practically topless, as her shirt is tied beneath her bust, has been allowed to stay on the site. Bar two bits of tape on her nipples, the woman's breasts are entirely bare, yet it falls within the rules, essentially on a technicality thanks to the strategically placed tape. Kendall Jenner, meanwhile, posted a provocative that depicts the side of her entirely naked bottom, with a car balanced on the top of one cheek, yet despite the stipulation regarding 'close ups of fully-nude buttocks', the shot has been deemed acceptable. Hypocritical? Instagram says it doesn't allow nudity on the site, yet enables shots such as the above to appear on the page of US poker player Dan Bilzerian . Only words, say Instagram...this image promoting the use of guns was published by user andygotphotos . Beyond the pale? A young user came under fire for describing her father as her 'man crush Monday' every day. This inappropriate post was then compounded by her hashtags that reveal she's at her great grandmother's funeral. Despite ongoing bloodshed in Syria, positive messages and pictures of the country's president, Bashar al-Assad, are regularly uploaded to the site, with no objections from Instagram .
