There’s a growing misconception that sites like Twitter are a good representation of unfiltered, unmoderated content, or that the only moderation actions from these sites is against famous figures like Trump.
In reality, sites like Twitter and Facebook remove a lot of terrible content posted by people who deliberately enjoy terrorizing shared spaces with abhorrent images.
Anyone who has been involved with the moderation of a moderately popular site or platform with image-upload features will understand: There are a lot of people on the internet with infinite free time and motivation to troll public spaces with shock images and similar content. Any unmoderated space will eventually attract these people.
Worse yet, if this behavior goes unchecked it tends to drive the good users away. Decentralized and/or unmoderated platforms seem to have a small following of ideologists who will look past the bad content and focus on the good, but the general public isn’t terribly interested in wading through random pornography or worse content just for the sake of being on a decentralized platform.
