thanks for this - I was confused about it since I have seen a few that looked very similar (first 12 characters of it the same) - did a quick, slightly deeper check into history and see that I do have 2 urls that have the exact same string, but it appears at least in this one case, that it's a click to a short link that forwards (dj-m.ag to djmag dot com) - so the similarity was confusing, and see some doubles freaked me out. now I see at least some differences in several - so I guess unless there is an easy pattern match, or as the title of this hn thread story suggests they may be able to reverse engineer fbook clicks - it's highly concerning to be sure since so many places use third party scripts and assets.

fingers crossed this is good and it gets better.
