When you post a link, PLEASE remove the "?" and the trackers that follow it.
Random example; I picked this link from Fakebook. You can see that it's from Fakebook because it includes "fbclid".
As well as showing that it's from a Fakebook user, it probably also includes other information about me. (Well, it would if I hadn't changed some characters!)
The link works perfectly well without the trackers:
https://www.quordlepuzzles.com/collections/store-closing
A while ago, someone here posted a link to Reddit. The trackers in the link allowed me to log in to their Reddit account and to post as them! (Naughty me.) So PLEASE don't do it!
Disclaimer: I have no connection with quordlepuzzles. It's just a random link that I picked.
EDIT: Youtube links do need the part with the ? in them. More specifically the watch?v=random characters part. Also might include a jump to a start time as in &time=456s
Thanks to u/metalheadtruth for reminding me!
To be able to login just from URL is just bad security implementation on destination site. They should be using local cookies, in combination with URL parameters as well as server side session variables to track the user login.
Generally there is no harm to use entire URL, at least not for posters. Most of the trackers only affect server side stats since trackers are added by the OP (the real original) to track clicks. Also, significant portion of the URL parameters are not trackers. Many times, they are control variables on how the page should display the content (could have search string, page format, page number or range, video start time, etc.), so removing them could mess up the page display and audience won't get the same result as OP. Best would be to test the "clean" link on a private window before posting it.
When I post, I do remove all the UTM tags, as they are used for the stats by Google analytics - only because I am aware of these.
Agreed, although I don't want a mobile phone type display on my 21" monitor if a tracker is telling the site to do that! (I don't think it does.)
