That’s my default answer for anything involving anonymous transfer of assets. Double so when you get a third party to act as the middle man.

I'm not a money laundering expert but I thought the point was to get a bunch of cash, from drug sales or whatever you don't want anybody asking questions about, turned into legitimate-looking income. Income from Patreon might look legit, but how would you funnel your cash into Patreon contributions without putting it in a bank account first (and setting off the very alarms you're trying to avoid)?
