Interesting, but are you suggesting (since this is in the suggestions forum) that WCG should be used as an active anti-spammer site? Is WCG enough of a target for spammers grabbing email addresses that this would be necessary?

Seems like it is easier to just ask people to realize that if they post their email addresses here on WCG or on any other site anywhere on the web they may have that email address grabbed and used by spammers, and they should post email addresses at their own rsk. I don't see where this is a problem that WCG needs to address.
