I assume the ban is quite situation, if you are caught knowledgeably trading with a marked scammer you will not receive a warning, however, in most cases you receive up to two warnings.

How do the admins know that you traded with them?

I was wondering if trading with scammers will get you banned on both Steam and TF2OP? I've seen some people got banned on TF2OP stating that "This is your 2nd time trading with marked scammers, and now this is PERNAMENT." If so, how does one know who traded with a scammer? Do the admins have some kind magic powers? (lol). And how do I know if the item I'm trading isn't scammed?
Just curious...
