Can old threads in non-hacking forums be closed?

[N9ne]

I'm getting extremely annoyed at the fact that people are becoming more illiterate by the day and failing to notice a thread's date. It's actually quite unbelievable, maybe it's a summer thing but i've seen old threads being bumped up in the lounge from months if not years ago. The best solution i've seen (they do this at SPF) is closing all old threads in non-hacking forums (ie. don't close them in the full releases forum) so that will prevent people from bumping them back up. Also, maybe a nice flashing yellow text page if they do try bumping is in order, to either blind them or teach them a lesson .

But seriously, it has got way out of hand.
