From the article, the data collection hinges on a bot going into a public server then scraping the history. Still a problem that Discord should act on, but it looks like there is no need to worry about private servers.
Does anyone know what kind of naming pattern or bot identification methods we could use? I belong to a small public server that’s there to serve a public need.
You could probably have a verification system thing that I've seen some public servers have where you have to complete some action before getting access to the actual channels.
