It annoys me, but what I hate even more are the people who post that "vs. threads are looked down upon". Versus threads are looked down upon by some people, and they aren't against the rules, so STFU already. If you don't like the subject of a thread, but it isn't against the rules, don't post in that thread and if it is against the rules just report it and don't post in that thread.
It's just like the idiots that post in troll threads with stupid comments like "obvious troll is obvious" or some shit and the thread just keeps getting bumped. They don't actually care about stopping the troll, they just want to make themselves look good in comparison.
