If you had given the whole IP in the first place you could have saved yourself some abuse. :-) You are right in the sense that it has been recommended for a while that ISP's filter invalid traffic outbound from their network, to prevent their customers from spoofing. However, given the number of incidents of hijacking recently, it's entirely possible whoever is using this actually has their own BGP feed.
