Nope, i never had that.
Other people will tell you to read all of their WP, team, and their project, is it good or too good to be true. But it doesn't guarantee you will be not scammed by them (many scam project even managed by some reputable member on here back then).
I only can say, it's based on your luck. There is always a risk to join in any campaign (including getting scammed)
I am very grateful for the response from friends, in the future I have to level it to read more detail while looking for more, may we all always be lucky and the process never lie on the results
