They actively collected fees for their Coinjoin, Paynym and some other services.

Some of these did not even require a central server (like Paynym, Stonewall and collaborative transactions) but a fee was still taken by Samourai Wallet developers.

They also have the capability to comply with the OFAC address list on their coordinator, but have decided not to.

Other things include that they possibly could have traced all of their users…

I sometimes can’t feel bad for them when they literally poked the bear multiple times, while also giving the government every excuse to shut it down, and also being extremely shady.
