>Something I have only just realised is that it might work because the email address given is fake so MEGA presumably wont get a response from it.

no shit but then it will probably send an email to the bonniebonkers protonmail...regardless of if the claimant is actually using that address...and we don't know who really runs that. If it's Seth, then he'll have your email. If it's Bonbi then she'll have your email. Then the question is: would either of them care either way? Bonbi might let if be put back up or she might want it to stay down. Who knows what Seth would do?
