I've seen a lot of my favorite affiliate marketers with 100K up to 300K+ followers just disappear overnight. Their account was banned so there might be some truth there. I don't know. Getting shadow banned means you can still post and you still have your Tik Tok account but it's not shown on the For You page which usually leads to way lower traffic numbers. Things that can cause shadow banning can include getting a lot of community violations for your posts.
