There are several reasons why bet365 accounts can be restricted, including matched betting, unreasonable betting behaviour, GamStop (self-exclusion), and exploitation of bonuses.
For example, Bet365 was taken to court for refusing to pay over 1 million in winnings to a horse bettor in Northern Ireland in 2024. The company refused a payout of 54,000 to a customer in England in 2024, a case which was still ongoing in 2024.
