How often were you scammed in the past considered in percent of all campaigns? How many were paid? And do you have an idea to avoid it?
In all of the signature campaigns I joined before and until now, I never get scammed even once (believe it or not). The secret behind it is always making sure that the campaign manager don't have a negative trust, the funds have an escrow and the payment rates are not to good to be true (not too high, not too low just the average). I also make sure that I only join in campaigns with reputable managers (e.g. yahoo62278 and Zapo).
I know that facing a scam is very hard to avoid but for sure it is not impossible to achieve as long as you are thinking twice for every actions you do
