(you're free to suggest this to /q/, Moot or mods)
If you don't want to people to resurrect old threads or prefer the content to be fresh,
Just set the algorithm for bumping such that each new post doesn't move a thread to the top
but bumps thread position one higher.
e.g.
thread #1
thread #2
thread #3 <--new post moves this thread to position of thread #2 which falls to #3
Currently, even captcha doesn't prevent necroposting. It is a flaw of many forums, but most have age limits (e.g. thread older than X days are not bumped).
