Aniwave and a bunch of other sites seem to have been shut down. They all have the same or similar goodbye messages replacing the site. People are speculating that its a major ACE crackdown, others are speculating that its a major hack. The closest thing to anything solid I’ve seen is that the mods of the discord are trying to reach the site devs/owners (https://imgur.com/uwBYLGg).
