What did he do?
When "Harry Potter and the Deathy Hollows: Part 2" came to theaters, Anthony put a filter on all amirite posts with the name "Harry" in them. If you put a post with that name, your post would initially say something along the lines of "This post could be a spoiler of the Harry Potter Deathly Hollows movie. Click to read". Lots of amiriters had fun with this block.
