Precisely. If any business was declared as a money launder or other criminal activity alleged against them, I would apply the only available logic and would stop participating in their signature campaigns. And add to that if allegations were made by forum members that they were scammed by any business I display in my avatar or signature then I will remove it and probably open (or at least participate) in a scam accusation thread.
The authorities in Germany and the US have clearly stated their opinion, and everything is written in a document that has been made public. Aside from what we here on the forum think about mixers in the context of privacy, some very powerful people think completely differently and consider such a way of privacy illegal. Therefore, everyone who has promoted CM over the years, and everyone who promotes any mixer today, is doing exactly the same thing - there is no difference or logical justification that one is different from the other.
I personally would not be worried about possibly being asked to hand over the received fees for the signature campaign but others might be. If asked by law enforcement agencies I would simply give it as I would not want to be viewed as a criminal or fugitive.
Having said, if law enforcement agencies made it clear they will ask Chipmixer signature campaign participants to send/surrender all funds they received from the Chipmixer signature campaign, I would immediately remove any mixer from my avatar and/or signature and never get involved with mixer campaigns again and that would only be because a precedent would have been set by the law enforcement agencies. As of yet, that has not happened.
Well, considering that the investigation was conducted for years, it is not realistic to expect that we will find out everything so quickly. At this moment, no one from the forum's administration has announced whether they received a request to hand over all the information that is of interest to the investigators, and even if it happened, there is no obligation for the admins to say it publicly.
I am missing something.
The answer was provided by another member, and I leave it to everyone to interpret it in their own way.
