Notes:

An observation on one example out of many. Mike Lamond, once a unique wholesome personality with many equally human followers, used to make Starcraft 2-related content from around 2010~2015 on a separate channel that peaked at over 900k subs. He suddenly stopped uploading videos for 3 years, and, in the same manner, took the channel down without a single peep in 2018. Another 7 months after that he uploaded a long video on his original Youtube account (also cleaned out) spending only seconds actually talking about the deleted channel itself (yet another staple trope amongst modern content creators). He also deleted his Reddit account and apparently all of his tweets.
