Right now, we don't have too much problems with spams, anti R8 content and the like. They always end up being deleted by the mods. Sometimes we get raids... But who cares honestly, they never last too long.
If we put too much effort into moderation by using a banned image archive or algorithms, other netizens will make fun of us. I think we should take it easy and let the mods do their work!! Honestly, where is the fun into maintaining an archive of pictures that we specifically dislike?
