Can anyone here explain why beware of an investor telling you they are buying more shares?

Is this a board for investors to discuss the company and how they feel about it and what they are doing or is it a board controlled by bloggers without a penny invested and only interested in manipulating your mind while dragging up news from past and ignoring any good news posted by the company?

Ignore the bashers here and focus on the good news posted by the company. I'm buying stock here because I believe in the company and its products and the price is right for me.
