Online gambling operator Bet365 is advising its Romanian players not to pay fines it says the government has no right to collect.

Earlier this month, Romania’s National Gambling Office (ONJN) placed Bet365 on its online gambling blacklist. The move puzzled most observers, given that Bet365 stopped accepting new Romanian customers a year ago and is believed to have paid around €30m in back taxes to quality for a new Romanian online gambling license.

Romanian media reported that ONJN had ordered provisional license recipients to cease all Romanian market activity for one month starting Sept. 10 and that Bet365 may have flouted this edict. Bet365 responded by saying it believes it has at all times complied with all legal and regulatory obligations and didn’t rule out the process of challenging ONJN’s decision.

ONJN also warned Bet365’s Romanian players that they could face fines of up to $2,600 if they didn’t stop accessing unauthorized gambling sites. Some of Bet365’s Romanian customers have since received emails ‘inviting’ them to ONJN headquarters to “clarify some issues” regarding their use of the site.
