(Maybe make this a poll?)
Since I phased myself out of the HBS thread, I actually haven't seen admissions consultants participating anywhere on this sub-forum. That said, with the exception of Sandy, whom I find sort of... alarmingly funny, I don't care too much for admissions consultants. It could be sour grapes 'cause I could never ever ever afford their services, and I do think they have valuable things to add. But there is already an entire GMAT Club forum allocated to their advice, free services, profile evaluations, etc. I don't think things are too crazy on this board yet but it could get out of hand if they all just hop in wherever. There are some well-established consultants around here but honestly at this point, I've gotten into a single top-10 school, I've read a bunch of books, edited my friends' essays: I could pretty much be selling myself as a consultant.
The question I ask myself mainly is this: what's their agenda? They're not here to be altruists, for the most part: they're here to drum up business. Whereas I really like to think that most of the participants on the GC forums are here for mutual aid and support.
