Bashers and pumpers, I believe, approach these message boards as if most retail investors are pawns to be manipulated.  I reject that premise, and refuse to engage them as it only encourages their persistence. 

Having said this, I also understand that some posters using different aliases will engage in pro and con exchages with themselves for the sake of keeping interest alive on selected message boards.  Similarly I judge this also to be a waste of time for both the poster and readers.

...my opinion, I could be wrong.
