Algorithms and evaluative criteria control what content is recommended to users on search engines and social networking site. These can reproduce stigmatizing discourses that are dominant within society, and result in negatively impacting LGBT self-perception. Social media algorithms have a significant impact on the formation of the LGBT community and culture. Algorithmic exclusion occurs when exclusionary practices are reinforced by algorithms across technological landscapes, directly resulting in excluding marginalized identities. The exclusion of these identity representations causes identity insecurity for LGBT people, while further perpetuating cis-heteronormative identity discourse. LGBT users and allies have found methods of subverting algorithms that may suppress content in order to continue to build these online communities.
