Avoid? For whom? The objective should be to reduce or eliminate spam, not pass filtering costs off on others. The "individual user" didn't solve anything, other than proving they fine with wasting others time and bandwidth. Like it or not you're advocating throwing trash in my yard for an "individual users" advantage. If these systems worked as intended, then no email would ever get delivered since any significant penetration would block challenge messages too. They were specifically designed to exploit the fact that most people won't use them. -- - Andy This is not the place to ask for a scooby snack or hand holding without getting attacked with a flamethrower. - Stack Smasher, Full-disclosure email list
