Is it possible that the mail address is guess-able? E.g. I'm sure that someone owns john.doe@gmail.com

They're Fastmail masked email addresses, of the form word.wordnnnn@fastmail.com - so you can enumerate the address space, but I would hope that they guard against that, and I got two spams within a short period of time to the same address.
