I agree I'm a little concerned that someone is "leaking" info but not pictures. It would just as easy to take a picture as it would be to post info
Some people are really paranoid about posting certain scans. The grimer was probably arbitrarily considered "safe"
There was one time, I think, where the PWT in BW2 was revealed, but the guy did a similar thing to now. Only posted one screen and was just text leaking otherwise. I think it wasn't until sunyshore went out and got their copy that we got full scans.
My favorite is the one time a guy got corocoro and was posting full page photos of assorted stuff in the magazine, but didn't post the pokemon pages out of spite
