If you're interested, there IS a way to get the money out of Betfair.
Start an account in name A
Nick a credit card in name B and load up B's account - let's say with £1,000.
Keeping the maths simple, Account B is used to offer odds of 2.0 (equivalent to evens in a bookmaker) on a snooker match for a total liability of £1,000. Account A matches it with a bet of £1000.
If player wins, account A has the £1000 that was in account B and can withdraw it.
If player loses, then account B now has £2,000 in it, so repeat with a bigger bet from the two accounts.
Eventually a bet will win and the money is transferred into account A and the money can be taken out. Some has been lost in commission to Betfair, but so be it.
That's a simple way of getting your money out. It leaves a massive audit trail, but the criminal is doing this with a bundle of accounts at once and hopes to disappear before being spotted.
