Teen-focused social network Habbo Hotel is opening in certain markets again, after revelations of inappropriate messages from older users to children forced the site to close temporarily. According to a report in TechCrunch, Habbo says it will reopen in its most popular markets, Spain, Brazil and Finland, with other countries to follow, as it attempts to prove that it can implement safety procedures to weed out content, users or messages not suitable for its young audience.

According to TechCrunch, Habbo-owner Sulake claims that it has improved the site’s safety controls, with better algorithms to pick up anything that could be deemed unsafe for children. Blocked or muted users must pass a test to indicate they can use the site responsibly, while new tracking measures ensure that it is possible to match activity to specific users. The site is also bringing in more moderators to police the site and providing a button for users to flag up unsuitable content.

Sulake was forced to shut the site earlier this month following an investigation into whether the social network was safe for children, with investors Balderton Capital and 3i subsequently pulling their stakes in the firm.
