When you copy a link from X, the URL looks something like this: the part you actually need: everything after the ? is metadata for X's systems, not for the post to load. what those parameters do: s= is a device and share method code. s=46 means iPhone app, copy link. s=20 is roughly web copy link. s=19 is Android. X uses this to measure where sharing happens and which surfaces drive traffic. a= (or t= in older versions) is a session-bound attribution token. it ties that specific share event back to your account or session. when someone clicks the link, X can attribute the click to the share, which feeds virality tracking, abuse detection, and internal analytics. The person receiving the link sees just the post, they don't see your username or account from the URL itself. X sees that you shared it, from which device, in which session, and how many people clicked it from your share. Delete everything from the ? onward before you paste.
