If you're in mixer signature campaign, now you don't have anything. There is no need to show initiative. Mixer campaigns is allowed on Bitcointalk as long as theymos won't decide different. If one day he will decide to ban mixer campaigns, then you wouldn't have to make decision to leave campaign - all mixer campaigns simply would end then.
What theymos told to staff members is different story. Bitcointalk staff isn't same thing as regular members - they can be considered as employees of Bitcointalk. Emplyees of Bitcointalk advertising ''money laundering'' related stuff - it can bring problems for Bitcointalk. While regualr members can continue advertising basically everything, not just mixers, but also all kind of scams.
I don't think theymos will stop Mixing companies to advertise their products in the forum, and the only time theymos can do that is when a president strongly confirmed that the mixing is a scam or money laundering company them at that time he might make a pronouncement to stop his members which he has done not to participate but to stop the company in the forum is what I can't not tell because All the allegations level against 1Xbit both the forum and outside the forum yet 1Xbit is still running well in forum therefore, the mixing company might still run in the forum but limited members will like to promote such a company.
And not Mixers companies are bad or have a fraudulent activities, some of them are genuine, so we can't use what happened in one to generalize others.
I think that you are framing this matter wrongly in a couple of ways Mate2237.
as far as I understand, theymos is an owner not a president of a company... so there is less requirement that theymos has to get anyone to agree with him.. a president of a company would have more need to appease shareholders and "the board" for example...
Another thing, there is no need to determine that something might be fraudulent or a potential scam in order to attempt to distance yourself from liability as an owner,.. and specifically we have to see the owner within the context of a service that allows for the sharing of information on the web. The removal of representatives, or agents or even employees (though they are most likely not employees) is largely just to create more of an arms length between what he (theymos is doing - or through his agents) and what users of the service (the forum) are doing.. yes, even mods are users of the forum service, so there might not even be any need for theymos from stopping what they are doing, but if he is trying to keep some distance between himself and what members are doing, then sometimes it may well be more prudent to recommend, suggest, order the mods not to engage in such conduct of wearing certain kinds of signatures (in this case the mixing services).. so may well just be a precautionary measure that may or may not be too much.. but surely discretionary..... but may well be prudent.. and surely I doubt that any law enforcement agent told him to do it or gave a warning, but you also never know that sometimes there could be discussions with government officials that are "off the books" and surely consultants and attorneys might have some ideas regarding some of the internal deliberations of some of the enforcement agencies, too.
