TLD .us is still full of bad stuff

This is why we can't have nice things.

Brian Krebs reports on research gathered by Infoblox showing a massive malware and phishing operation using thousands of short domains in the .us TLD. Stuff like this is why some spam filters treat some TLDs more harshly than others; if most of the references you see to any .us domain are spammy, it might make sense to just treat all .us mail as spammy.
