but, out of curiosity - why would an account get closed down because it was a business?

It was a personal account. I used it to gain info for updating mister.red (purely non-commercial)- its name was Mist Er-Red. They offered to change it to a business account.

In the wake of Russian abuses thereof they were increasing their activity, but being in-adept they went after soft targets. As if the St Petersberg Mafia aren't one step ahead!

Yea, Yea we understand the process. It closed because I refused to give them any personal details that could be used to triangulate to anything like a bank account. Security begins at home! Not at Fakebook. Big targets attract big players and many of them. It only takes one success. Apologies are no barrier to the miscreants.

Martin is better off without it for those reasons and all the others listed herein.
