For a while I've been getting blank messages from two numbers I don't know. I have an iPhone, if that matters.
I guess they're not really alerts, but these two numbers and their blank message screens are always seen in the message app. Earlier they were at the bottom, now at the top.
Has anyone seen or heard of anything like this?

I can block them, but I'm curious. Guess I'll just have to block.
