If you right click/copy "link", your user id is appended at the end of every link you create.

e.g. <https://stackoverflow.com/a/271517/111307>

I am 111307, and **I** have nothing to do with the question linked here or its answer, of course.

I am not hyper concerned about privacy, but why? What's the point of this?

I'm assuming this is some kind of way to figure out which users are bringing traffic. Are we going to get rep for this or something?
