There were three major exoduses of reddit people to voat and similar sites, years apart. The first was when reddit cracked down on paedophilia, the second when it nuked fatpeoplehate and associated subreddits, the third when it banned and/or hid some of the more egregiously Nazi-oriented subreddits. The third was probably the largest and most influential, but yeah, there’s other horrible stuff on there.

Of course, all of this makes for a charming community.
