I don't think they'll be implementing that. While you'd think it'd work at first, it wouldn't because people would just reinvent slang continuously (or use different spellings) to do so.

Obviously this would only be known by a smaller group up to date on the slang. It would prevent people not in the know from searching. However, this would also make it harder for police not in the know to search for it and find it and bring the person who possess the media in for questioning.

I wonder why it's illegal anyway, since watching something doesn't actually do anything to anyone, the problem is the things that have already been done. The vids are evidence we could use to stop it.
