Seizure of website - no one would lose any sleep over that. It would also be exceptionally easy to prevent. If you don't know how/don't think so - forget it

As for fincen I'm positive the lawyer he's been dealing with when asked about it would've shrugged it off and not looked into it, and if ya believe that I've got some land at the bottom of Australia I'm trying to sell.
Gotta love the absolute idiotic mire that is bureaucracy over there (not saying here is in any way exempt either).

I probably wouldn't spend the time putting forward documents either if it wasn't required to be public with them (if they are/were required) and instead invest my time a bit better.
