Or at least make the marketplace view able to registered users only. Not sure if they run adsense on this forum but making the entire forum private could be a bad idea due to loss of ad revenue from guests.
Either way I don't think IG is scouting the forums to find random accounts to ban. Every account I've mentioned on here has not been banned, I've barely mentioned 1 of the ones that got banned and never mentioned the other.
I'm not saying it's a bad idea but I think it's a conspiracy theory at this point to assume the usernames were handpicked.
