It’s a simple trick that takes advantage of the way that Flamebate removes quotes when you quote a post. It removes the first quote-opening tag, the last quote-ending tag, and everything in between, whether or not those tags are actually used to form a quote. I tried to include the source in this post, but when I looked at the preview, I saw that apparently [ youtube ] tags aren’t affected by [ code ] tags, so it didn’t work properly.
