Years ago, before I started blogging but after I started paying attention to politics on the internets, there was some Freeper freakout over something innocuous that happened at a school and they were getting a lot of harassing phone calls. This was in the earlier days of the internet, and I figured that the school officials probably had absolutely no idea where it was coming from. So I emailed and phoned the principal to let them know. They didn't have any idea.
Anyway, point is now schools probably know when these freakouts happen because they're fully mainstreamed.
