All online bookmakers now recognise that for some people, gambling ceases to be fun. For those people who wish to restrict their gambling, they provide a self-exclusion facility.
Self-Exclusion is a formal process where the bookmaker no longer allows you to operate an account with them for a minimum of 6 months and maximum of 5 years (your choice of time period). During this period, you will not be sent any marketing material and that company will not accept any bets or deposits from you. Once you have self-excluded yourself, this cannot be reversed for any reason, and you will not be able to open a new account during that period either.
