I've been watching watching the YouTube channel Blameitonjorge for a quite a while, ever since 2014, before he really blew up with his Top 40 Lost or Banned Episodes of Kid's Shows video. I have noticed that over the years, some of his videos have gotten unfortunately deleted, a few of them being his vlogs and skits from 2013-2014 (which have most likely gotten deleted due to the sudden change in content in early 2014, therefore not really fitting on his channel anymore). However other videos, like multiple videos from the series of videos aptly named "Creepy Videos on the Internet", might have gotten deleted due to mass-flagging, or to even greater extent, his older videos being content-claimed as mentioned over his twitter. It can be inferred that due to the claims on some of his old videos, in fear of them hurting his channel, he could of taken them down. Although it is not confirmed, and sounds like an empty conclusion, that's what I'm sticking by.
Here's a lazy article I made a couple years ago, you're welcome. However since then, more of his list videos from 2014-2015, as well as a couple from 2016, have been deleted, possibly due to the aforementioned content-claims. If anyone in question has a good list of lost videos from his channel, it would be greatly appreciated.
