This is terrible. Someone with access to server logs at a few web sites (or someone that loads a third party resource (ads, analytics, sharethis buttons, etc) onto a few web sites) would be able to know exactly who is coming from fbook and viewing different types of content.. no inside access to fbook or their data required.
I can't believe nothing is auto-stripping this url addition between firefox and ublock origin - must find and tell others.
- _-___________-_ 7y agoNote that the ID changes for each "click" - hence "Facebook CLICK ID" - so you can't tie different clicks back to the same user without access to Facebook's data. But yes, an extension to strip these (along with `gclid` from Google, `reddit_cid` from Reddit, and so on) would be very welcome.
- stevenicr 7y agothanks 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.
