We're up to 22 for the day so far. What bothers me is that they're starting to use US based ISP's, which makes it very difficult to block email originating from those ISP's - we don't want to block REAL geocachers from logging on.
We had a case recently where one of our well-known members was blocked from the site because they changed ISP's - to one that was blocked a long time ago before we really knew what we were doing. LOL!
