Gambling regulators in the Netherlands have slapped a record fine of nearly half a million euros on the operators of an unauthorized online gambling site.

On Tuesday, the Kansspelautoriteit (KSA) ordered two companies behind online casino site Redslots.com to pay fines of €240k apiece for promoting the casino via a variety of Dutch-language sites and offering new Dutch punters a signup bonus.

The two companies behind Redslots – Redcorp SA and Bluemay Enterprises NV – may sound familiar, as the KSA fined them each €130k in October 2014 for similar shenanigans involving 7red.com and RoyaalCasino.com.

The KSA said it began its latest investigation in November 2014, suggesting they didn’t have much faith that the original fines had convinced the companies to stay on the straight and narrow path. The KSA also claimed that its latest action indicated that just changing a domain name wasn’t enough to throw their bloodhounds off the scent.
