Up until like a year or two ago, YouTube links always used to be pretty clean. The format was youtube .com/watch?v=[video_ID]. A year or two ago, they started adding a tracking suffix on, so it would be youtube .com/watch?v=[video_ID] &si=[tracking_ID].
Over the last day or so, I’ve noticed links with a different format, youtube .com/watch?v=[video_ID]&pp=[tracking_ID] - only the pp= string is much longer than the si= string. This can only be because they’re including more information in it. What that information is is anyone’s guess.
This is basically a PSA to watch YouTube links more carefully, as people are by and large complacent with them (moreso than other links) and never even realised the si= change, let alone this new pp= change.
It could also be that the change to pp= is meant to circumvent communities, like this one, which automatically filter out the si= suffix. They may have decided to address that, then took the opportunity to make their tracking more severe.
It encodes the contents of the search bar.
E.g. for

Oh, that’s how you get it. I just tried it and got the regular si link which doesn’t seem to have valid b64 data.
that’s interesting. do you perhaps also know what the si param contains?
No, I don’t know. If I had to guess,
simight be short for something like “source identifier” and just contain some unique identifier to track who originally shared a link that others are using.
