I already posted a solution for this in an other thread but looks like GT admin doesn't look at that thread; if they would block new registerd users ( not the full access ones ) for a period of 2 days from posting in the forum then this would all be history, these people register and then post theire shit and unregister again because they don't want the email ( IP adress ) to be visual for to long to avoid tracing them down so they most certainly will not leave it here for 2 days or longer.
