FYI, that ?is= parameter at the end of the URL exists exclusively to track you and the people who click it – namely it’s a unique share ID that points site visits back to you.
For example, Alice shares a video with Bob with ?is=1234. Bob follows the URL with that unique ID, telling YouTube that he got there thanks to Alice.
