Humph. My home IP address which is shared by thousands of random people behind two layers of NAT, in Brazil, gets a score of "63, low risk". My mail server, on Linode in the US, which has had the same IP# for about 20 years and sends mail to GMail and Microsoft without problems (and only from a small group of people who never send spam) gets a score of "0, high risk". This is useless garbage, and dangerous to boot. The last thing we need is more arbitrary and unaccountable "reputation scores" being propagated by self-appointed and unqualified reputation judges.
