I myself is also part of the signature campaign which promotes gambling but I don't feel guilty regarding my comments on this forum because this is first and for most a forum wherein we can say our opinions regardless if it's negative or positive. Besides the opinions that we are giving are useful opinions to the benefits of our co-members here. I don't think being part of a signature campaign prohibits a member to say whatever they want to say, signature campaigns are like advertisement that we promote.
yes sig campaigns are like promoting something but let say you promote a gambling site and you always say that playing a gambling is bad because it is risky and you will only loose money , with that , do you think you are promoting in a good way ? people will think that gambling is bad and they will stay away on the gambling scene , there is no way that they will click on your link but if you will say positive things about gambling , you can attract people to play gambling and they will surely visit your link . if ever the gambling site that you promote gets alot of costumers , they will even increase your salary and they can run longer which is a good thing for you , am i right ?
however your right that this is an open forum and you can say what you want but you should only say negative things away from what you are promoting .
