- people who enter a character/ship-love thread just to hate on it (or likewise for hate threads). what is the point of this, you'll just get downvoted and your pleas fall on deaf ears lmao
- when it comes to nsfw fics, noncon and dubcon for abusive ships. it can be done well, maybe, but I haven't seen it if so.
- the fandom tearing at each other's throats about who tops who in a shipping. I won't even be subtle here, this is literally MikaYuu vs. YuuMika in a nutshell - don't join the Owari no Seraph fandom.
- canon x canon fc kids
- hating on a character just because they go against your OTP (cough Kikyo in Inuyasha cough)
- gatekeeping.
- every best friend pair in canon is secretly in love with each other.
- agreed with @AceofSpades on every hc being 'they're trans and I will fight you on this'.
- also agreed on others about child x adult ships.
