Tumblr
Tumblr has been quite popular site in the feedism community, and one of the few that makes content publicly available by default. Tumblr is therefor one of the sites that is easily critized by outsiders of the community, such as this video by READY TO GLARE from 2018, titled: Why Tumblr sucks ep.24: Feederism which has over half a million views as of 2024.
In December 2021, Tumblr banned a whole lot of hashtags for compliancy with the App Store rules of Apple. It was quickly discovered that feedism related hashtags were included in this. However, it is possible to workaround this limitation by using multiple hashtags at the same time.
