I've also almost grown accustomed to the occasional call from "Microsoft", who are kindly inquiring how they can help me with my Windows computer problems. (Hint: No techsupport on Earth will ever call you voluntarily. Ever. And nobody can tell whether you have computer problems or not unless you tell them - they just want your confidential data, your money, or probably both.)
Now, however, the schemes for quick money from people not paying close enough attention have reached the snail-mail stage. A while ago, the Most Patient Husband Of Them All received an actual on-paper version of the classical Nigeria Scam (he did somehow not feel inclined to write them back to claim the several million Euros that he could have because the original owner went off and disappeared or died or whatever). And I received an extra special bit of funny spoofy spam yesterday:
This very officially-looking letter requests me to send back my information... to list my business, and especially my VAT ID Number (which nobody but other businesses for B2B-transactions ever need, or are interested in) on their website. For just under 400 € per year, plus VAT, and for at least two years.
Well. No thanks, guys.
