Austria’s government has proposed allowing internet service providers to block the domains of websites deemed to be breaking local laws, a category that could include internationally licensed online gambling sites.

Austria’s Ministry of the Interior recently announced plans to amend the Telecommunications Act 2003 to permit local ISPs to use “traffic management measures” in the prevention of “criminal acts.” The official proposal defines such acts as malware distribution and other computer crime, along with copyright infringement and dodgier forms of pornography.

While gambling wasn’t specifically mentioned in the proposal, the recently formed Austrian Association for Betting and Gaming (OVWG) is sounding the alarm that gaming sites are at risk of being blocked should the amended Act be approved by Austrian legislators.

Despite its questionable efficacy, domain-blocking has become increasingly popular in many European markets, with the Czech Republic, Slovakia, Switzerland and Poland all having joined the domain-blocking party this year alone.
