All I can say is I run a business and whether a customer is right or wrong, you treat them with respect and communicate that accordingly. I'd like to see what my potential clients or clients would say if I said to them stop spamming me.
I appreciate your help Igor and understand you're inundated with requests, but writing a blog post like this really sends a bad image.

I agree with the comments about Agents, it doesn't seem to work, its a nice idea. But whats the point if the agents are too busy see more to respond, or too annoyed about getting similar questions.
