Yeah I think community level policing is a good way to move forward. If someone wants to create a post a pic of your lunch community I may not upvote those posts personally but if someone else sees it as valuable and wants to upvote it they can, that's what stake here is all about.
I guess the simplest thing that we all ask for in art posts is honesty so we can know what we are voting for with confidence. This is meant to be a social community and sometimes people want to just have fun and I think we lose sight of that sometimes.
