...we can't afford any mistakes, honest or not. You can make sure that a picture-post is allowed by finding the name of the copyright-holder (using Tineye or Google Reverse Image Search), and checking it against the prohibited content list in the forum rules...
Well, never let it be said I was **86** to try out a new tool...

Wow - I am very much enjoying this "reverse image search" utility and am appalled it's taken me this long to discover it. I'm not sure yet how useful it will be for figuring out copyrights, but it's extremely handy for ferreting out smut blogs. *Joy!* If the consequences of a mistake are so dire, perhaps a good step to take would be to post these tools on the banned content page? It may not fix the problem of "difficult to track" copyrights, but it would empower clueless-yet-well-meaning people like me to make less work for you.
