I agree with you; I'm also just leery of setting a precedent of doing something like this, negging all the members of a campaign, because who knows if the next project someone thinks is a scam will actually be one?  In this case, I'd say the evidence is solid that 1xbit.com is indeed a scam, but I still have reservations.  I'd much, much prefer that Theymos act like a leader and ban the campaign outright rather than just deny them advertising space.  It would seem like he doesn't want blood on his hands (or at least perhaps the legal liability if there is one) but is content with allowing other people to advertise a scam project/exchange--just like he's content with allowing scammers to operate freely on this forum.

As I said, I have no problems with anyone who tags the campaign participants; I just don't like the potential ramifications that might stem from that.  There was a project once that cryptodevil swore was a scam, and he'd warned all the campaign participants that he was going to tag them all--and he is/was on DT.  It later turned out that the project wasn't scamming anyone, that it had been a misunderstanding (and it was so long ago that I don't remember the name of the project, but I think it was one of the ICOs).  My point is that he was on DT and had influence over a number of other members, and had they bullied people into ditching a campaign that they thought was a scam, everyone would have lost.

I'm glad this thread was started, because at least it allows the 1xbit.com campaign participants a chance to see it and respond (or get out of the campaign before their reputations are reddened).  That's the right way to go about it if any tagging is to be done.
