It's comparable to 8Chan or Gab or Voat - it's a refuge for all the people who have been censored from places like 4Chan or Twitter or Reddit, and it turns out there's a reason why those folks get banned from such sites and when you get them all together in a room, predictable things happen.

(This is one of the few examples of such sites showing technical competence, so I wouldn't put too much stock in their decision to go with Heroku, and I wouldn't worry about your own apps.)
