I think the rules are generally fine, although I can only read the top line, I had to create a quick test meme to see the "be respectful" "nsfw" kind of rules... The only things I'm not 100% sure about as those can be kind of subjects that can easily go out of hand are politics and religion. As long as those subjects can be memed without much trouble I'm fine with those (I made fun of a Dutch politician myself here, and I do not wanna be a hypocrite), but if trouble arises, an update can be required. What do you think?
