Seems as if a simple waiting period or review of each post before allowing it on the site will quickly stop this nonsense. It is done on many websites and discourages the sort of people inclined to stir up the crap because they are juveniles and as such require immediate gratification in the form of seeing their garbage posted. The left is terrified of Palin and will stop at nothing to destroy her once and for all. They are aware of the recent polls that show her as the 2nd most admired woman in the country.

These people are not juveniles. They are paid antagonist who push the Socialist agenda. This is about discrediting anyone who supports Governor Palin.
Most of all, anyone they see as a strong leader to revise and push forth the Republican party will be subjected to much the same.
The owners of Team Sarah should have been prepared for this, because, as we all know, Obama has 3 million cyber geeks out there to attack anyone who disagrees with Obama, shut down any website that is disagreeing with Obama, and skew polling data.
