A Brazilian judge passed a preliminary ruling which would lead to the removal of two anonymous messaging apps from the Apple, Google and Microsoft storefronts in the country, after it emerged they have been used for bullying.

According to a report by Estadao, Judge Paulo Cesar de Carvalho asked for Secret to be removed from Apple’s App Store and Google Play and for Cryptic to be removed from Windows Store. In addition, the ruling required the remote disabling of all installations of the apps on smartphones in the country.

According to 9to5 Mac, Apple has a blacklist of apps on its servers, meaning iOS devices could be alerted to a banned app and refuse to launch it. The company is not known to have used this capability before, but Google has remotely blocked apps from working in the past due to malware problems.

If the injunction becomes law, the companies will have 10 days to delete the programs and will be fined BRL20,000 ($8,868) for each day beyond this that they remain available.

A source told 9to5 Mac that Secret’s maker has sent legal representatives to Brazil to find out what the situation is, although the ruling appears to apply to Apple, Google and Microsoft as distributors, rather than the developer itself.
