A request to ignore all users wearing their signature is also an alternative if they don't take this post seriously.
A request to whom? Anybody reading this thread can ignore all the signatures they want, but the problem is obviously that most members don't have signatures on ignore and will therefore be exposed to the posts made by all the members of the 1xbit.com campaign--and some of them might click on one of those signatures and potentially get scammed.
Personally, I don't care if JollyGood or anyone else tags every single participant, though I wouldn't feel the need to do so myself. There was a similar situation with the last Yobit campaign, and I'm of mixed feelings about punishing the campaigners rather than going after Yobit or 1xbit.com or whoever else is accused of scamming. The reason for that (which many of you probably won't agree with) is that just because you rent out your signature space, it doesn't mean you endorse the service that's being advertised.
It's tantamount to boycotting a TV station for allowing [pick your controversial company] to buy an advert slot when that company has done something shady. It happens all the time and to me I'm fine with it. Everyone should do their own due diligence before buying a product or using a service that's advertised on a website/TV station/wherever.
