I guess it's either because of these and one of the ways to ensure your promotional method is legit is to ask your affiliate manager. Apart from knowing the whether the method is legal in the eyes of the network, your AM will sometimes give you tips on how others had promoted the offer as well. Anyway, TS, if you want to know why you are suspended or want your account to be reopened, kindly call them at the support line. I am sure that they will give you a second chance if you properly explain yourself if you are not at fault.
