The debit system for sub here in HK is only possible on the user side. You can't automate it like in Europe, the dude has to go to his own account and register it himself with the company's target account.

But what you say must be impossible in SEPA too - to fake a sub registration you'd have to register with a corporation ID as a subscription receiver in the SEPA area. I'd suppose at least you fraud one person you're immediately found. But it's also that you probably can't even register without at least a sort of reputation check.
