I have to say, that, although I have not frequented this BB for any great length of time, the extent of ridicule does not seem particularly great. Clearly people are looking at different timeframes and have many different types of methodologies, so differences in opinion are natural. Are you suggesting that there are members who intimidate other members?
Many years, when I traded FTSE, I used to post on the Hemscott BB. It became apparent to me that there were three posters who were getting price sensitive info on an Israeli tech company (Geo Interactive media now Emblaze Systems). Not only were they in receipt of such info, they were posting it up on the BB. I remember posting a message to the effect that this was utterly wrong and there could be an FSA investigation. As a result of that post I had 92 vitriolic posts threatening me and calling me just about ever name under the sun. Now that is unpleasant.
PS The CEO was called up by FSA and I think the LSE too to explain what was going on.
