Posting on old threads

Why is it your see some people act like a ass when people post on old threads.
If the thread is worth talking on seems fine to let it continue on.
Yes i have seen people post on threads from over a year on forums, but if there still here and not locked or deleted then there open to post on.
It's called site management to clean up junk, trash or even stale posts when they feel like it!!
Well just one man thinking out loud here so feel free to reply with your thoughts or even flame (Like my CYBER feeling will really care)

because they know most likely they can piss somone off and not get their ass kicked...good topics do need to be discussed over an over more but not too much

Actually in a debate thread, I think it is acceptable. If you have something to say on that topic, it's better to bump an old thread then to make a new one.

If you guys every see anyone necro a thread, just message me and I'll ban them. Only report if a ban is necessary, if their response is valid then don't bother.

yes its posts on a thread from 2005 that says "Thnx"
there is no need to post thanks on old topics if it was that great +rep it and save every 1 the agro of starting up more bs. these days if you post stop necro there will be 40 1 posters after you saying "yea you fucking choob" if there is a reason for them to be banned Paroxysm will do it if there isnt a reason he will prbly do it anyway

I always see this some guy recently posted on a thread saying nooo from like 05.
