If you're referring to the question from Louisiana, since there's no link provided, let me try to recap. A home seller asked if there were any discount brokers in his area. He received 6 responses. Three were from agents in the area who said, "Contact me." Three others were from agents in other states who cautioned against making a decision simply on the commission rate. They also pointed out that commissions are negotiable and that you "often get what you pay for."
The questioner then posted another question--complaining about "spam" from out-of-state agents. He clearly wanted a direct answer to his question: Where could he find a discount broker? He was irritated that out-of-state agents had responded with what he considered to be irrelevant responses.
If that's the question you're referring to, I defended the out-of-state agents for providing useful information.
But you raise an interesting question:
Are posts with names, phone numbers web addresses, e-mail links, and more spam?
Or are posts that don't specifically address the precise question asked spam?
Regarding that first question, it's a fine line. Someone could simply post: "Yes, there are discount brokers in Louisiana." But that might not satisfy the question.
Or: "Yes, there are discount brokers in Louisiana. Please contact me for more information."
Or: "Yes, there are discount brokers in Louisiana. Contact me. John Smith, ABC Realty, 123 Main Street, Anytown, Louisiana. http://www.JohnSmithDiscountRealtyLouisiana.com."
My personal preference would be for that second answer.
Hope that helps.
