forums lock themselves after XX days
 

any way of doing this so when a thread hasnt been relied to for XX days it will lock itself? i see alot of spammers bringing up old threads

IMHO there is no point in locking the threads after a certain amount of time: It will block new answers and what's the point of keeping the threads in your board if they will get no answers anymore? ;)

If what bothers you is thread starters who are bumping them up, I suggest you applying this hack
