It's a canned response. I think that message includes mention of "spam." I got the same thing on mine.

But I just shared this one - from the sharing button, not a pasted link. With text. Tagged you. Did the same on LinkedIn. Let's see what happens.

So far, both posts have gone through. I have 1 view so far on the LinkedIn post. (Again, I usually assume no one there pays any attention to me at all, because I usually just DON'T post there. For 15 years, I've treated it like a Rolodex. I know a loaded gun when I see one. ;) LinkedIn is a trap for the unwary. But then, so is any social media, right?
