General information about Concentric.net

Concentric is a large isp with a good abuse policy but very poor enforcement -- to the point of being borderline rogue. Update: Concentric has increased its fines for spamming to $1000 per day. See their Terms Of Service

Reports include spam from "Daniel Elder"'s porn site which is now hosted by Concentric after having been disconnected from Softaware.
