Used to be the spam calls would kind of go away for awhile, if I just didn't answer the phone.

Then most started sending a text if I didn't answer.

Now I'm getting spam with a very weird phone number that always rings and rings, until the voice message begins.

These numbers start with a V and a lengthy series of numbers. V60718394800015 is the latest.

I just don't get it. what are the people behind this crap hoping to get?
