Recently, I posted a question on Android SE here asking what was creating gibberish files in my SD card. It got a few hundred views, but also attracted a lot of "answers" as comments. Can it get protected? I can't do it (not enough rep), and the question needs it.
Though the system does this automatically after a certain amount of deleted answers (IIRC it was 5, but yours currently only has 3), I've protected it now on your request.
