Not entirely sure which specific name you are talking about in this case, but you are correct that certain services are off-limits to discuss on webmasterworld. One particular "information scraper" that I tried to discuss kept getting the '#*$!' curse-word treatment by the forum software as well. Off limits topic.
Maybe someone out there does not like bad press, and applies pressure to not get their name found in discussions on a web-search? I guess only the webmasterworld powers that be can answer that question.
