If they can't say which bank it is, or what the reason behind it is, or anything like that, it's probably that someone somewhere suspects money laundering.
I don't know about where Null is, but here in bongland money laundering rules are thus. If you have reason to suspect money laundering (large cash transactions, payments in cryptocurrency, money coming from or going to a high risk jurisdiction for money laundering, politically exposed persons being involved, transactions that make little commercial sense, etc.) you have to report it up the chain and the person at the top then decides whether or not to make a disclosure to the FCA or NCA. However, regardless of whether one is made, you can't tell anyone, ever, that you've made a money laundering report as that's tipping off. You also have to stop dealing with the subject of the report.
From a risk viewpoint, the Farms could well look like money laundering. Bitcoin is accepted. Laughing at autists may be amusing but it makes little sense from a commercial viewpoint. It's a place for money to go into and not come out. Now you know and I know that it isn't money laundering because there's not all that much scope for the placing and layering that characterises same. But imagine some cubicle drone looking through all this and not using their brain because they're not paid to, and there you have it.
