I aggree it's stupity and BS..
However..I have been through this..I run a web site also. That there are similar threads anywhere else is not a defense.
The other threads stand on there own..UNLESS..alleged to have been after the thread here and related by a poster or mod OR admin..or less directly a reader..then it becomes the planitiffs issue of harm...with discovery of course.
The issue as Jon states is clear..no false statements by anyone other than the SB posters..or allegations without merit are cause for frivilous suit.
"But Dad..the other kids are doing it..is not a defense."
One of the best checks I have cashed was a judgement against a plaintiff on a suit deemed fraudulent. Court costs, attorney costs, my time..my staff..and a nice punitive judgement..
Attempting to stifle or "tie-up" in court by means of fraud or frivilous suit can be rewarding to the defendant..
