That is kind of how the whole, "Paid bashers" rumors thing started from. They are not technically paid to bash, but they have their own agendas which is making money like the rest of us haha.
I don't think SA has enough cred to sway the markets. Most of their commentators are hacks. If you want to laugh hard or just want to find someone to hate on find "stockcreeper" who blogs on SA. Complete loudmouth moron.
