Tower Gaming Rackback Responses

[MissionToMars]

hi,
i asked a few times for RB on Tower ! The offers i got were between 30-50 % Rackback. The problem is you dont know the persons offering it and they can talk alot without proving what they are offering.And i dont want to play a month to find out if i got cheated again or not.Does some sites offer tower RB so its more secure than private persons i do not know?or is it possible to get some feedback from person which had no problems with their affiates?
