Of course i don't.
CAT architecture is perfect in term of user security.
I wrote few Rules in Term Of Services, and i apply that rules as a "non-human" algorithm. All CAT users that decide to replace API got the same treatment.
This is what i call "intellectual honesty" : clear rule, same rule for anyone, no discrimination.

My rules are simple :
- When i made a mistake/when i create a problem -> I pay/I Fix/I Check
- When other services/system create problems -> I Don't pay for them.

Current problem it's very unlikely to affect your API Key, but if you want to change anyway your api we could discuss a lower price.
That's because i understand that a real problem occurs, but you must understand i must not fully pay for it.

Thanks
