That's a little overly dramatic. Use your hide/mute button for people who abuse Unicode like that. Come on, people, the entire reason you have all this freedom now is because you can also deal with that kind of crap yourself. Hide/Ignore feeds into multiple other systems that contain that very kind of spam. FYI: Being able to use extended Unicode in the body of your post isn't a glitch, it is a feature. Just like image posting, though, if you annoy people with it, they're probably going to hide/mute you, and if that is done enough, the system will put you on a global ignore list (kind of like how mutes worked in Reach). It is a minor issue if you do it in the subject of a topic, but even there it isn't too big a deal.
