There seems to have been a lot of spam recently, particularly the bumping of old threads to advertise something.
PLEASE can you work out a way to highlight old threads so MNers don't spend hours reading through them. You already have the facility to highlight the OP on threads - It shouldn't be that hard to do something to change a thread to slightly grayed out if its older than 6 months. IF something 200 days = blank. Or something. PLEASE.
It would also discourage the spamming fuckwits.
