I think this purely a resource issue, eglug have limited disk storage resources, and we cannot keep spam stored.

Problem is, spam is as they say in the eye of the beholder. If I can hide posts I consider as spam I have no problem, as far as I care problem is solved.

For example, when I selected several message in my hotmail account and click the button "this is spam", those messages disapear, I dont really care, if they are still stored, but if I have a pop3 account and store email message on my disk i would want em really removed from my disk

I think we can use to collectively fight spam, the user can mark a message as spam, and it should disappear from his screen only, other users will see it, if a message hit a certain spam count it can be physically deleted from disk, spam count should be visible to all users, and user should be allowed to revote on the message, this will give the opportunity to legit poster to defend their messages if they see it reached the deletion mark

by doing this we can eliminate the need for moderators, we only need to agree on a reasonable spam count!

but as long as we have moderators, we must allow anonymous post, to put controversial posts anonymously
