Uh, I'm pretty sure that's a prank edit or something on Wikipedia. I've been following Treehouse TV pretty closely and never heard of a show called Batmen Behaving Badly. Ben Andrews Matthews doesn't ring any bells either. Check the edit history of the Wikipedia page; someone's probably having a laugh.

Haunted? Really? C'mon guys, shows are weird cause of budget cuts and odd creativity, not curses. But hey, I'm new here, maybe that's the charm of CBBC that I'm yet to get XD
