If I try to reply to something very old, a warning appears at me... perhaps something could be added to this message about the OP being inactive...
But there are also people talking in the thread, I don't know if it would make sense, sometimes the OP doesn't even participate anymore... but the topic continues
To me nothing is needed to added to this because this everything clear to everyone except such a person is a spammer or something good, they won`t bump just thread. This is not base on inactive members only because there so many other post of such were the Op is still active but that thread is still very much old.
I think the best option is to report thread to be lock, were its clear that there is already an answer to the OP post and others continue to make an irrelevant reply similar to this shared by
LuciusEven here, people are replying without reading anything, so maybe it's just an outdated idea for an outdated forum.
I guess this is inevitable in every forum, some read the Op post and ignore others replies while others read only replies before making their own reply.
