new spam tactics

I just got a call from someone claiming to be a “domain notification server”. They had pulled our contact information off our domain record, and had a highly deceptive pitch, something like:

We are calling you to alert you that you will be receiving a notification regarding your domain, blah blah blah information from our domain record. Please give us your fax number…

Only, more misleading. I was like, Is this really about my domain? Is this a DMCA notice of some sort? Is this a spammer? To the direct questions: “Do we have an existing business relationship?” the person was confused and couldn’t really answer off-script. To be fair, “Alex” wasn’t speaking in his native language — clearly Indian, so could have been US-based or outsourced. Eventually I got enough information that I determined with 98% certainty that this was spam, and told them to take us off the call list. He said he would, which confirmed that it was indeed spam.

wtf? We’re on the do-not-call list. Is this a racket anybody else has encountered?
