1. What kind of assistance would you appreciate to protect ML readers from
spam?
2. When handling email spammers I realized that some of the spammers can't be
blocked due their spoofed email headers. Either the spammer victimized some
other services OR have put invalid information in the header. Some of the
spamming network put fake abuse complain OR email address removal system.
Sometimes they even pretend to be an ISP and assures that they disconnected
the malicious user whereas they are the ones who were spamming. So there were
some cases when a spam coudn't be prevented.

3. Don't you log forum user's IP? Are you finding abuse@ from IP?
Sorry for the long message
