Used to work - very - closely with Prime Trust. They typically lock accounts if you’re:

- Laundering money, which involves weird behavior like sending tons and tons of txs to “other accounts” on the same IP address, fund-washing, etc.

- Constantly overdrafting your bank account to purchase Sats, but then burning the bank account -> rinse -> repeat.

99% of the time (in my experience) they make the right call, but have seen them mess up, too.
