Help "Quackwatch" Defend Themselves from Litigious Quacks

As fully outlined here on Derek Lowe's blog “In the Pipeline”, Quackwatch is getting sued by some quacks because he highlighted their use of a misleading diagnostic and how it could be used to push unnecessary and potentially dangerous treatments on clients. Quackwatch have a Paypal donation system, so if you feel like committing a fiver to their defense fund, I'm sure it'd be much appreciated. After all, I'm guessing there's more money in quackery than in exposing quackery!
