Scenario 2 would require the person add the RMT to their Friends List.... In any case I guarantee they ban buyers as well. It just takes a little longer to snag the buyers because they have to have the evidence. Half the reason they leave some bots etc. up is so they can follow the gil trail to the buyers. Use the collection bots to find the gil distribution characters and then the buyers. Also pay attention to the RMT posts. There ARE filters but the RMT use half gibberish and begin or end their messages with a unique string of five or six characters so each post appears to the game to be a different post.
