When Q poasts hyperlinks, sometimes they are for a mobile app, and in rare instances they included tracking fragments.

Everything after the # is not even sent to the webs server – it is a tracking id interpreted by JavaScript (and sometimes used in older software to manage 'history' in Single Page Apps). You can put anything you like there and get random numbers all over their logs too.
Tracking Fragments send a message – they mean, everyone who clicked this link got that link from the SAME SAUCE.
