If you got banned by Tesseract, your posts would not be visible to anyone using Tesseract as their frontend. Even if you were not banned by wherever you are trying to post, explicitly blocked by the Tesseract user, or filtered out in some other way, your comments and posts would be hidden. And this hidden centralized blacklist was unilaterally administered by the dev of Tesseract.

Full disclosure: I got a regex on the blacklist 😁
