  • “Moderators — Moderator bias is a real issue. I’ve made harmless comments on posts that are clearly spreading hate, some get upvoted, others downvoted...”
  • “Bad mods — Mods remove everything they disagree with and mute you”

  reviews
  • “Exposes Location — Since when did fizz become like instagram exposing locations? Absolutely not, from anonymous to pinpointing our exact location. Nope.”
  • “Beware of privacy problems — I’ve heard that while they “guarantee 100% security” there are some serious privacy concerns including that posts may not be fully anonymous.”
  • “They sell your data and the posts are clearly fake and made by the mods. Just some low tier Stanford idiots trying to get one over on you.”
