Don't feed the trolls.
There is a nice little option called "ignore user".
To find this useful little feature, click on a post, and under the posters username, click on "User actions". Then choose the option "ignore user", it will make your stockhouse experience so much more pleasant.
And for goodness sake, please stop REPLYING to the trolls. You're not going to change their mind, and it's clogging up the board.
