It depends upon the campaign requirement. Some gambling campaigns require their participants to gamble as a part of their rule.
Really?! I also advertised many gambling sites for the past 2 yrs. (because my early years here, gambling sites campaign are not yet on trend, ICO does) until now but I haven't encountered such requirement. One of the requirements I unusually experience is the use of their own wallet but other than that everything is the same with a common sig campaign

. Can you please site examples, I'm curious lol.
That kind of rule has never existed in many signature campaigns I have participated, they will not force you to gamble, in fact, the requirement is just very simple, they just want you to wear that signature and do what you usually do in the forum, if you are constantly posting in gambling boards then you continue that when you are in a campaign but the campaign itself would not tell you to gamble in their site or a particular site just to be eligible.
