Give aways that use the forum to post usernames are against the terms and conditions of this forum. This can not only get the OP member banned , but each and every person that posts their username to this thread can be banned.
Mind letting me know where in the "Terms and Conditions" (which I can't seem to find

) this is mentioned?
I have absolutely no reason to believe anyone in this giveaway will be banned for participating in this giveaway.

One post per day is reasonable.
That said, if you are posting for posting/activity and not really for participating, that is a different case.
