I don’t share your opinion on this matter, so I don’t know of one off the top of my head, and my quick search yielded no results.

Normally I’d say “Be the change you want to see.” and encourage you to create a community for it yourself. However, you should probably ask yourself first, whether a community dedicated to hating something is even worth having, and then ask yourself if it is worth moderating. I can’t imagine you’d have any real great conversations when it’s all going to just be “x sucks” you’d basically just end up with the same post over and over again.
