A private bank was a very good idea, they should be resistant. Things like Julius Baer have accounts for very shady and very rich people and don't care if they can post on the dead bird app or not. If you are the kind of person who can get an account at a private bank it should be ok.
The LLC in WV doesn't need a registered agent and lists only post boxes as its addresses, this is all fine as long as no actual US laws are being broken on the forums.
I find the .pl choice risky though, it is a country where, e.g. "offending religious sentiment" (any religion) is a criminal offence. There is no Section 230 there. WHOIS shows it was registered by a German Company - and in Germany "incitment to hate" carries a mandatory prison sentence from 3 months to 5 years.
Like someone says, Europe has strong hate speech laws - and not only that, also very strong privacy laws i.e. anti-doxing - and they don't care if it's publically available information.
But let's hope it lasts.
