Why do members hijack threads?


Some members intentionally start conversations on threads that are unrelated to the Original Poster’s topic. Not only does the thread get derailed, but whatever useful info discussed on the thread by the hijacker is hidden from view, unless one searches for it. 

So rather than starting a new thread on topic, some members appear to disrupt an ongoing discussion.

Thoughts as to why this occurs?
