There are many reasons you should not consider trying to get around the Bet365 terms by creating multiple accounts. It is beginning to sound like you want to commit fraud against them, possibly for the very generous promotions they have on offer and that is a very bad idea. The reason they have limited you is because they don't see you as a profitable customer, so obviously you're taking money from them and they'd rather not have your business. If you're thinking you've found a loophole to exploit for cash, it was probably an intentional feature designed to draw in genuine gamblers. To them, you fit the profile of a profit taker and not a profit maker - they have many ways to track you outside of documents and if you start multi-accounting then you might lose lots of money in future.
