@tchambers it uses mastodon software so it is said to be mastodon. As mastodon instances block it, does it remain “a mastodon instance“? I would say that mastodon is working as designed in that undesirables can be blocked. If the Gab or any other group sets up using whatever technology, they can exist in their own bubble.
The emphasis should be that the Gab is not mastodon, it uses publicly available software and is its own network.
