What is going on with eBay and sharing contact information.. that ISN’T contact information!

It seems almost every question I answer eBay has a little orange pop up that says: “Sharing contact info isn’t allowed.  You must complete your transaction on eBay.

Here is an example where a buyer wanted to know if I had a tea cup and saucer that was in the stock photo.  I did, and sent the buyer a link (on eBay) along with the eBay item number.  eBay didn’t like the link OR just the item number.

Here’s one where I was giving the buyer a tracking number.

Have you had this happen to you?  It’s allowing me to send it with the information anyway, the warning just freaks me out a bit.
