I've resisted it for a while now, but it's time.
I have added the first DNS TLD to my spam filter.
I have yet to get a single e-mail that wasn't spam from any domain under .info. Not one. It's proven to be one of the best positive indicators of spamminess I've seen in a while now.
There are some .info websites out there that are, well, informative. Which is good. But if anyone can list any legitimate source of e-mail in the entire .info zone, then list it in the comments. Because I ain't seen one yet. And as things stand now, I never will.
