Looking at Dutch regulations, probably a wash. Latest General Banking conditions are from 2017 -
Link, p65 onwards. They emphasise that both the bank and account holder have a 'duty of care' and the bank can yeet you unliterally if you breach it. They are vague about what breaching actually constitutes other than withholding information about transactions and real financial crimes such as money laundering - but there is some talk of 'damaging the bank's reputation', which seems like bad news.
For what it's worth, ING are opportunistic borderline criminals who have no problem hosting terrorists and international drug criminals and protecting them (settled for hundreds of millions multiple times after investigation), and they seem to be protective of smaller/normal customers too, so it might be worth looking into ING specifically. They host all kinds of trash so they wouldn't object to the Farms on principle, but I don't know what they would do if someone started emailing them with complaints about gamer words etc.
Recently ING froze the account of a famous Corona-truther, but this was because he broke the banking rules by not supplying information about where his money came from, which conflicted with an anti-terrorism law.
