They may contain interesting or useful information. And someone may revive them.
>that prevent people from making new threads
What?? Nothing prevents you from making new threads, and thus sliding old ones. So, a good solution would be to allow much more threads, so that each thread has enough time before being sled for people to archive it or revive it if it is interesting/useful enough.
Though another good solution would be to have automatic archives, like there are several ones for cuckchan.
