This thread can be getting worst if you ask people to post their username, don't you know what spam means? Even worst you replied to those posts one by one in a row which is obviously against the forum rules because it is bumping your own thread more than one per 24 hours. If you want to give away no deposit bonus codes or free spins codes, it's better to create a new thread at the Games and Rounds board.
It is just a friendly advice, as your account can be banned if you keep on doing it.
