I never understood why forum admins hated this so much. If I have an update to an old issue, why shouldn't I post it in the same place? Why create a whole new thread?
I've seen fora so ADHD they lock threads after a month or something. This is comical, given I work in deployment and management of enterprise OSes, which typically lock versions as maintenance branches at the start of their support window. Solaris10 will die after a TWENTY-SEVEN YEAR support window, but it's typically a decade.
But if "necroing" is to update a thread after an arbitrarily-short time, and if people get banned for it, then the admins of that forum are naive and stupid. The way I solved a problem with my TheForeman installation (what junk) a few months ago leveraged something from 20 years ago.
I'm a fan of usenet's "comp" tree, anyway. Forum threading has always come off as weird, and the format has always seemed a little emoji-heavy.
I think it depends on the forum. On the forum I am, there is no search timeout and necroposting is allowed as long as you bring something relevant to the discussion. And if you accidentaly create a new post that should have been somewhere else, the post is simply moved there.
