Legal... in your disclaimer is this line which I think is what any normal person could add 2+2 = conflict of interest on a stock board that you moderate ... "PSPG, may at times be compensated for profiling companies on the web site and/or, message boards, etc. and may obtain positions in the securities prior to the posting."
There is no way to get rid of the seed of doubt when you are being compensated and then mod a board where you can control information content at any time. Sorry, it's just way too obvious what people have a problem with concerning compensation.
