A few searches indicate this isn’t totally new, I’m just getting it for the first time. But I’ve just received an invite to “ATM PAYMENT UPDATE”. And the description was one of the standard spam texts: “This is to officially inform you that we have verified your
contract/inheritance file and found out that why you have not received
your payment..” etc.

The efficacy of spam overall still boggles me. I don’t doubt it works, or it would have stopped by now. I would think someone using an online calendar would be a tiny bit more savvy. I’m probably wrong. :)
