When you share a YouTube video using the share button it adds “si=some_unique_code” to the URL. If you don’t remove that it shows your personal account to anyone who receives it so that they can chat directly with you. For a lot of people this is their real name.
I’ve seen it all over Lemmy so I figured I’d mention it here! You only need the stuff before the question mark in the URL to let others see the video.
This can also be turned off in your YouTube settings under the privacy section. The setting is “channel visibility for shared links”. It will still add the si code for tracking though.
It should be common practice if you commonly share links. Try removing the query string (everything after and including the question mark). See if you get to the same page. If you do, don’t use the query string.
Query string parameters are rather often used for tracking. Look for gclid parameters after you click a google ad, for example.
The harder ones to bypass are Facebook and Reddit share URLs, which give zero indicator of their destination; it seems impossible as the recipient of such a URL.
At least with bit.ly, one can add a
+to the end of the URL and see data on it, including the original link (to then safely access without adding to its click counter).Yeah, there are always ways… any service could easily generate unique paths that require a server-supplied redirection to the main target. Then the server just needs to stitch up (1) where was that link generated and (2) who arrived at the redirection page. Users would have no way to determine the target link without exposing themselves to being tracked.
A platform like Reddit can do this too, by replacing the links you put in your comments/post, so they redirect to the original link. They can even make it continue displaying the original link, while actually linking to the redirect page.
