Rather than trying to run the guy out of town, why not start a "better" thread, showing accurate, unambiguous entries, clear stop-losses, and clear and unambiguous exits.
With the exception of the almost defunct Live Trades, NVPs thread and the Dax thread, people have no option of seeing a daily trading thread, warts and all.
I think the better option would be to render a thread obsolete by providing a superior one.
Rather than the simplistic haranguing of someone who has a popular thread.
I find the guy in question interesting, but wouldn't trade any of his calls since I too find the calls flaky. That's no reason to want to wish ill on the guy.
