22Bet, Bet365, Betfair, Meltbet, and BK8, are some of the offshore betting sites accepting players from Indonesia. Indonesians use VPNs to ensure the authorities don't catch up with them to access these sites. The implication for this is that punters in Indonesia are not protected. If an overseas online betting site withholds their money, there is no legal route to help them recover their losses.
To prevent such a scenario, any Indonesian punter needs to pay due diligence when choosing a sportsbook to bet at. To sum up, betting is not as popular in Indonesia as it is in non-Islamic states, but there are millions of Indonesians who bet at offshore international casinos.
