Those would be considered unflagged. I know this because there were two different people at VGC Fall Regionals that had perfectly identical teams, both were hack checked, and BOTH of them passed. (Weird, I know, but it happened.)But if you mean Pokemon that were copied from the game, put online, and put on another, it's nigh file trading, something common among traders. Don't take my word for it, but I think they would be unflagged.
DNA said:I believe dummy GTS servers would end up getting flagged as I've heard about things like this in the past, though I could be mistaken.
