Thus far no one who has threatened us has done more than initial discovery motions, so, for now, we wait . You can bet that the community will be hearing from us if we ever need a legal defense fund. Given that the number of spam victims numbers in the tens of millions, we suspect that the spammers don't want to sue us because of the popularity of our cause. What their customers do is add rather than remove these addresses. Removal is hard.
Addition is easy.
You can try the same experiment we did. Create a new e-mail address somehow. When you're sure it's working, post it to a so-called remove list . Stand back and watch the spam pile up. We anti-spam workers are well known to the spammers and we are costing them a hell of a lot of time and money by making their work difficult.
