Pro tip: clean YouTube links. When you get a link from YT, it includes an ID tracking back to YOU. It's a "query string" on the end of the URL like this:
...?si=[tracker_ID_here]
This ID allows YouTube (and their owner, Google, and *their* owner, Alphabet, and ALL of their associates) to track the people who click on the link, and the apps they used, back to you, building a network of none-of-their-business.
Good news: DELETE the "?si=..." part & the link works just fine without the tracking.
<< "si" typically refers to a parameter used in the URL for tracking purposes. YouTube URLs can contain various parameters that help track user interactions, such as views, shares, and other engagement metrics.
For example, a link might look like this:
https://www.youtube.com/watch?v=VIDEO_ID&si=some_value

"si" could be used to identify a specific source or campaign that led to the video being viewed. The value associated with "si" can help content creators and marketers analyze the effectiveness of their promotional efforts. >>

@VisualStuart all this still doesn't include all the other trackers and queries not encompassed just by the 'si' acronym, nor speaks about shortened links: which are naught but nice looking boxes full of shit
