Just so others don't have to discover this: even if you block Threadreader, they will still harvest your tweets. You have to do "@ThreadReaderApp BLOCK ME".
Why would you do that? Why do people have an issue with Threadreader? A portion of Twitter users seems to really like it. So why not let them read your tweet storms that way?
If I wanted to publish a blog post, I'd do that. When I put something on Twitter, it's for a reason. I also dislike Threadreader's assumption that they get to monetize my content for free and without permission. If somebody would like to build a business on my work, they can start by asking.
