This is not a complaint (since I have successfully bought codes from you previously). However, why do you want to set your thread to self-moderated? It seems to be a very strong predictor of scammers, since only scammers want to suppress all negative information on their thread. Most, if not all, of the scammers here use this trick to make their scam threads appear more legit to newbies, while making anyone who's been here more than a week avoid them like the plague.
Since it's very difficult to contact the moderators and here are many spammers I prefer to moderate the topic by myself. It's easier and you don't need to wait.
It's recommended to use a middleman if you're not sure that seller is reliable, in any case.
