Necro'ing threads

[gryphons53]

not even sure if this is possible or not, but is there any way that on certain sections (exploits, bots, scams maybe) threads either auto lock after a certain number of days since last reply or from start date? I've been noticing a lot of new accounts appearing the last few weeks that just randomly open something thats been untouched for months and out of the blue their first and only post is a "thanks for this" on that post. someone did it to one of mine so now I know its not always people being rep hungry making alt. accounts to bump their own stuff
