Definition of blacklisted bookmakers

Blacklisted bookmakers are online cricket betting or other sports betting companies, or sports books, which engage in fraudulent or dishonest conduct.
There isn't a central authority that blacklists bookmakers. Bookmakers are blacklisted by gaming regulators in a specific region, but still be considered legal in other regions. In addition, bookmakers may be informally considered as blacklisted once they have attracted a high enough number of complaints from users. A variety of behaviors can result in a bookmaker being included in a blacklist. These include:
Operating without a license – this may mean that some bookmakers are blacklisted in your geographical region but not in other regions. Violating good conduct rules, including cancelling bets or changing the rules that apply to a bet after the bet has won. Providing very poor customer service or consistently failing to respond to customers. Frequently being unable to pay out funds, or withholding funds. Serving as a front that allows for the confiscation of deposits. Mismanagement, resulting in inferior service delivery.
