What entry? If it's the head-case entry, then someone is fucking with us. We should put a call in to wikipedia, and get that traced back. If it's the head-fi entry...well, technically, even that entry is public domain, and the head-fi martinets shouldn't be allowed to take it out, but then, it's wikipedia, so anyone can do what they want.
Technically, it's not advertising, but I could see it as being not apropos to the head-fi entry.
