I'm not too surprised, in America alone here are thousands of anime lovers, so to see a fraction of them join this fanclub isn't very out of the ordinary. This is a well-organized fanclub.
Look at the fan number, 9000 duh. Unless your seeing an extra 0, cause really it only says 9000. You should look at that at the top right corner and not what somebody else is saying, it's only 9000, less than the Pokemon fan club.
