They seem to be 3 or 4 active users, I think I know @Wigglehard@exploding-heads.com if he was on votal. One of the most active at the moment. He is far from a troll. Though he may hurt some people's feelings, he will defend your Liberty of speech.
Now something related : will we ban "fat_people_hate" ? We will ban jokes on any minorities ? Where do we draw the line ?
Something is clear in my mind : we have to band apology of genocide, war, call of violence, and such. We have to ban what would be illegal in many civilized countries
