Company officials are not afforded the same degree of protection from personal attack as other users since they are public figures. That does not mean that users have a blanket exemption; they should still exercise common courtesy when addressing any user.
Whether referring to a specific user or a group of users, pejorative terms such as "pumpers" & "bashers" are almost always either off-topic and/or a personal attack, particularly on company specific boards. Those boards are about a stock and the company, not about other users.
