I see a lot of posts on DP that bring 5year old threads back alive which are obviously are not anymore interested to the original poster or anyone else. Such as if one had a domain name for sale listed 5 years ago, there is no point of asking today if it is still for sale (which causes the thread to get updated and other people start to reply to it assuming now that it is fresh). Considering this, would it be reasonable to display "THIS IS A FREAKING OLD THREAD" warning popup to anyone who attempts to post a reply to such thread that have not been updated for years to make sure they realize what they are doing? Would be a nice feature to add. Just a suggestion.
