Shadow banning has various definitions. The typical definition I encounter is how it works (worked?) on Reddit: you could see your own comments and posts when logged in, but no one else would. The "shadow ban" on Twitter that's garnering so much attention was manual down ranking of content. I'm not even sure if it's productive to call this shadow banning. Some content is given more visibility by the algorithm than others. Nobody is surprised by this. The main distinction in Twitter is that the downranking was manual, done to specific accounts. This realistically can't be detected, not evaded since abandoning a popular Twitter account is not an option. And for famous people, the downranking would be applied to their new account anyway.
