The only 'bashers' the SEC is after are those that post 'false information' concerning a companies operations, etc. 'Bashers' that post about the share price, etc., that's just speculation the same as if you posted it's going to da moon!
Now that being said, the SEC would have to prove a person was being paid to bash. If they were not, there is really no case unless it's a liable suit from the company.
