Things I have problems with:
Author not knowing the lore of the game their doing even with crossovers
Nazis and Neo-Nazis
Things that are Illogical
Twitter RPs
Racists
People being mad over something stupid or trying to get their way.
FemiNazis
Overkill fics on good fics that aren't expected out of Wattpad even on Fanfic.Net and A03 it applies.
The stupid Mcguffin when it's unnecessary
Tourists to fandoms who divert it to fucking politics than run away
Readers stories with no interesting takes
Authors with egos
