This could end up being very messy for a lot of members in the forum that participated in their signature campaigns if the FBI and US justice department decide to force forum members to repay all the money they received from Chipmixer as signature campaign income.
How do those that participated in the Chipmixer signature campaign feel about this? Do you think you will be asked to repay all the money you received for promoting Chipmixer since the FBI and other international agencies have attributed them to money laundering?
Since a lot perhaps most people are not under FBI jurisdiction I don't think any are worried.
As for paying back, there have been other mixers seized and nothing happened to the people wearing those sigs.
There have been scam ICO / IEO and everything else shut down by authorities and nothing happened to the people wearing those sigs.
There have been cases of casinos shut down by authorities and nothing happened to the people wearing those sigs.
And so on.
