Anyone else getting the 'spam' bomb threat?

I've now heard from several operators - our selves included - about getting an e-mail bomb threat to our datacenters asking for $5,000 USD or the "bomb will be detonated". Is this being seen on a wide spread e-mail blast to the RIR contacts, or am I just unlucky to know like 6 other data center folks who have also gotten this e-mail? It seems like a very odd/bizarre spam/threat campaign which would carry significant jail time.
