I've actually pulled votes from a couple that were stolen porn once it was brought to my attention.
The thing with steepshots is just that, even though you can make a good post with it, most people just do the single pic with no supporting information and little wording. So it ends up being like a simple tweet. Once the manual thing is going really well I may opt to bring it and dlive back. Not till I know I can curate them all though.
I would talk with some of the creators about adding more relevant supportive info to their posts. This is the one thing I see that they could still get black/watchlisted for.
