Far more than half the posts on this board belong to this board troll, and yes, many are posts simply responding to other posts made by the same person.
He's really sick, and since March he of course has added many aliases since he loses them often when people complain to Yahoo about TOS violations.
Note that on the list it is noted that any user ids with the words "chimp" and "greedy" are the troll's, and he is using those here big time.
Also, he is fond of using the phrase "retail market ignorant" and since we tracked him here from the IVAN board, we know that he used the phrase there too. You can use the search for the words "retail market ignorant" on the IVAN board and see that some of the posts are made by aliases on the list I just provided.
This info is for the purpose of adding to your ignore list the aliases he uses.
I will get an updated list soon as possible. Right now I am spending most of my time making up with my ex-partner Jeffrey Friedman. When that project is resolved, I will give you guys an updated list of trolls here. I have done a great job of hunting trolls on IVAN. You are welcome to come over to that board to see my handiwork. I am awesome, if I do say so myself.
