New bank account + new address says you can re-join as a new user againYes. I did it for some time over the last couple of years, however over time I lost accounts ("no more free bets" etc). I made £2k from it, easily.
I've moved since then, have a new bank account etc and sometimes wonder if I could create new accounts... but I'm wary of it.
