What is it with these “logo kids”?

So there’s this community of 9 year olds on YouTube that started around 2017-ish who are obsessed with tv logos, go animate videos, object shows, making rant videos, screen recording other people’s videos and reupload if then under a weird title, klasky csupo, Nickelodeon and nick jr, and then always have usernames like “thomasthetankengine29271919” or something. And always have a Nickelodeon or Cartoon Network show profile picture. They always make “logo effects stuff” where they take tv logos and make compilations of different weird effects on it. And have random ocs (original characters) of object shows. And make rant videos, and hate on popular YouTubers for no reason. Is there anyone else who has noticed this?
