I hate that too Dave. 
In all seriousness, on another forum we had some great fun with threads I started having to do with custom runs I was planning. Folks felt they had some input, which they did, while others could vent about what they didn't like. All in all these threads were well received because people got to do what they come to forums like this for in the first place, talk about guitars.
I know there are some that would rather not have dealer involvement in a forum like this, but in my experience they are the minority. Good news for guys like you is not many dealers bother to participate so you will only have to put up with a couple of annoying dealers like me. 
Members who are specing out their BTO don't want dealers jumping on threads to tell them about the one they just ordered for someone else, nor do they want dealers trying to sell them when they are just trying to get questions answered.
Would I prefer to have dealers on the forum, no okay, maybe to answer general questions, "is this offered on a bto?" or "is the 700 series going away?" or "what's causing this buzzing sound?", then yes. Do I personally want you or Jim or MFG answering questions with a bent on selling me something, no. This would include even if the dealer is a sponsor.
I do not believe that I'm in the minority on this here based on the many private emails I've gotten here and on the other forum over the last year. People grow weary of posting if they don't feel they can post without someone trying to sell them something and that takes away a great deal of enjoyment to the forum for many people.
For almost all of us here this is not a business, it is a hobby we love and want to talk about with others just like us. We should be able to do so without the shill all the time.
