The FNaF and Undertale fanbases are both pretty obnoxious in their own ways. I should know, I am/was a part of them. And it's not just the unsupervised kids on YouTube who eat up FNaF videos, etc. that's bad about them
There was also that incident in the Steven Universe fandom that left a bad impression (it was instigated by rabid tumblrites, you can probably imagine what happened).
