The way I have set up the market so that there is some self-control/personal responsibility baked in and to try to mitigate issues with "bad shit", is that I have built in block lists and keyword filtering.  That's what I'm working on wrapping up now.  So that end users can block markets/vendors/listings as well as do global blocks by keyword filters, and then their node won't store or relay that stuff.  There needs to be some kind of ripcord that people can pull whether for moral/religious/personal or whatever reasons to "opt-out" of stuff they find offensive or legally questionable.  So filtering in the hands of the users is my solution, this way its decentralized and the network can just self-police itself.

I'll put together some screenshots/marketing slick type graphics soon.
