When clicking on the share button below a question or answer, the number after the last slash is the id of the user creating the link. The link also works without this last part. Why does SX include user information in the link?

    various statistics are gathered "behind the scenes", including how many of a participants suggestions are viewed by other participants. this is just one of the possible bits of information collected. Sep 20, 2016 at 17:09

There are some badges which are awarded for your promoting the site (Announcer, Booster and Publicist). These work by using links with your ID in them: the site can only know that you've done some promotion if there is data to show this. Of course, you can happily delete the user ID part of the link: they still work just fine.
