e-bag selling questions

So I listed a car last week, set a reserve, and let it go.
Didn't reach reserve, and I'm not being ridiculous with it, I know its not worth what you have in it, what it would have sold for in 2006, etc.

The problem: all of the messages I get are ridiculous;
Please send me your phone number- from a guy who's been a member since 2007 and has never bought or sold anything!
What do you need to get out of it?
What's the reserve set at?
What would you sell it for locally?

OK, so I won't be sending my phone number, but if I wanted to disclose the reserve, or what I 'need to get out of it' I would have listed it as $X.XX amount or best offer.
I've sold and bought many cars on-line, and if I'm interested in a car- I give my number and go to see it, then ask what they want for it or make an offer.
And sometimes I just bid up to what I would pay for it and let it go from there.

How do you guys respond to questions like these?

Basically, I just didn't because no one seemed serious.
