Please search "message board bashing" on any search engine and you will find the answers to most of your questions. You will also find articles disputing the practice so you can read, compare, and make up your own mind. However, you can take into account what has happened on this board to help formulate your conclusion.
Before I, and others in this string, began posting on the subject, yaya/sherm posted hundreds of posts every day and thousands of posts every week on the GG board. yaya/sherm would use various alias' to post his nonsense. There was never any substance, analysis, or basis for this mindless dribble. He's smart enough to know that if he starts citing false statistics, reports, etc., he will violate the law. So it was just a constant barrage of "GG is going down," "I'm shorting now," "gold is in a downward trend," "I told you so...listen to me," etc. thousands of times a week.
Since our posts brought light to his activities, he rarely bashes hoping that, in time, everyone will forget and/or go away and then he can start bashing again. He continues to post, but sparingly in comparison, and primarily using the "good cop" sherman alias to try to gain the confidence of the board.
Now he hasn't quit bashing. He's just gone on to other boards using different aliases to make his money. It' simply not cost effective for him to try to fight this battle so he'll try to wait it out occasionally using "sherman" posts to further his goal.
Please do your research, rely on what has happened on this board, and apply your common sense to help formulate your opinion.
BTW: I sold my GG shares in Oct 07 and have no "dog in the fight" so to speak. The fellow is just so obnoxious that I like to drag him into the light so others can see him for what he is.
