Removing old topics that have been answered

I suggest deleting old topics that were answered in Movie Questions.
There are a lot of topics.
I suggest deleting only those topics that have been answered and are already 1 month or 1 year old.

Sorry, I have not at least 10 posts to post links. Movie Questions - it means here: movieforums.com/community/forumdisplay.php?f=23

Why delete them? Maybe somebody looking for the same movie will find the answer.

I'm happy to entertain any suggestion, but my question is the same as Minio's: what would the benefit be? People do come by and find films they were looking for from old threads, and sometimes people just find films they're interested in.
