I need help finding a website that I can share/post amusing funny stuff?

I currently use a website called Sharenator to post/comment on amusing/interesting things but lately it has become overrun by trolls and kids.
If I stay on there any longer I run the risk of getting into an internet argument (and we all know how futile they are) or be accussed of grooming someone and I want neither of those.

So: Where can I share or post amusing and interesting things with other adults?
