Now I truly want to keep everyone's attention on one thing!
As it seems, there was a signature campaign in 2016 from a bitcoin mixer that seems to be closed as for now. Check Bitmixer.io signature campaign.
This company was paying users automatically from the website. So, I assume users were receiving bitcoins that were mixed and more likely some users would end up with bitcoins that were used for black market and other illegal activities. There are a lot of old forum members, so, has anyone ever had any problem from the payments received from the bitmixer campaign directly from the bitmixer website?
I think that case like this can be a dangerous. If you are promoting a company that the government thinks is a money launder machine and at the same time you actually receive a laundered money from that company, then you probably are in a huge trouble.
I think that this worries don't apply to those who receive money from the campaign managers.
