When Is IMessage Not IMessage (When It’s Facebookexternalhit 1.1) \/\/FREE\\\\

So I was surprised, to say the least, when I sent a link over iMessage that I knew would be unique, but saw a request being made for it by the facebookexternalhit/1.1 bot user agent. This URL should not have ever been seen by anyone but me and the recipient. I took the time to verify that the only access to this URL was by myself and the recipient.

I have looked into this user agent a bit (see: here and here) it seems to be an IOS imessage utility function, though it it still unclear what exactly causes it. Is this traffic normal, should I have any reason to be concerned? 2b1af7f3a8
