It may be that there is some rule that says just giving someone a check doesn't count as "voluntarily disclosing" your account number.
Ah that’s the key though, you have to tell them to reverse it. I think you have 60 days in most cases. But the onus is on you to dispute the debit.
Hence why I avoid ever linking my bank to anything.

If you admit to handing out signed blank checks, I would hope that most if not all banks would at least have a discussion with you about how you may be not the customer they are looking for.
