I blacklisted about 300 IP addresses in the last 4 days, which is good. The new version of the Spam Project database will actually log a lot of information about the spammer, including whatever content they've submitted. It's nice to get a bit of information to make filtering a bit easier.
Oddly enough, the content is originating from Asian-based communities, including groups of Asian students studying here in the US. I'm not saying that all Asian students are doing this, but the majority of the content is coming from these groups.
I've taken the liberty of compiling an e-mail to the public contact at these universities, informing them that such content is being hosted on their servers, and that there is a definite issue with them. Hopefully it'll get something done to bring this down a notch.
The remainder of the hits are coming from random unpatched forums or web proxies, so it's going to be hard to notify anyone.
