Those whose accounts got red tagged two or three years ago know what the disadvantages of joining in such a scam tagged campaign are and how they can't find a different campaign thereafter. For those who are rushing into it now, I can only say they shouldn't jeopardize their account by joining. Steer clear of such. Scam is a serious issue here even though it's not regulated and I honestly don't know why it's that way.
What do these accounts do once 1xbit closes up shop? The answer is fade into the background and disappear. They will never find another sig job on the forum unless another site with a bad reputation appears. So ruining your account(no matter the rank) is a silly thing to do. It makes me want to believe the conspiracy that all these accounts are owned by the same farm.
@OP I see 1xbit being advertised on a few different sites. I was checking out a couple of my transactions last week on blockchain.com and seen 1xbit had advertisements there as well. So it's definitely not just bitcointalk. The only way we can fight them is by not joining their campaigns, but some have already shown that they value money over morals.
