I was going through my YouTube subscriptions on an account that’s been active since 2010ish. I didn’t recognize several accounts at all. They had deleted all their older videos and changed their account names.
I found myself subscribed to things that I would never have subscribed to. Either I had done it accidentally or they changed their name and took their videos in a different direction.
It’s a bummer because there are some old videos that were pretty funny/creative and now they are just gone.
