People should post in their signature campaign thread that they are a scam
you should visit their signature campaign thread. you'll see a lot of people posting warnings and their opinion about the signature and the website.
and that anyone who will join their campaign will probably never receive a payment for their efforts.
that's hard to tell, they might get paid they might not. besides. I think they are prepared to take a risk if they are still willing to join the campaign and ignoring the red flags presented by other members of the forum. so let them be and if they are not paid, those members who joined will most likely remove the signature themselves.
