Kiwi Farms
In 2022, Cloudflare removed them from their DDoS protection due to a online campaign. It later had a blackhole placed on its domain name by Tier 1 ISPs, such as Lumen, Arelion, GTT and Zayo. This was unusual, as there are only 15 Tier 1 ISPs in the world, and Kiwi Farms does not break any laws. Eventually by routing through other ISPs, the forum was able to get back online.
