Let's not see this degenerate into the usual name calling. I was just interested in what was so onerous or unusual about the request from PP. I've been asked for documents by Bet365 and Victor, but both were the usual requests of one doc to prove identity (e.g. Passport) and one to prove address (e.g driving license, utility bill, bank statement). Pretty standard stuff, though both requests did coincide with four figure withdrawals. Incidentally both accounts have since been restricted/closed.
Not that you're interested, but since you asked, I am a senior economist at a FTSE 100 financial services company.
