Oh man, you should never read Doctorow's Little Brother. Well, you should, because it's great, but it will freak you the F out.
I can see why you would be surprised. Here is a checklist of how to see if you are discriminating against a class of people:

I love this idea. I don't mind you selling the ability to contact me at all; don't listen to these other internet clowns. Now, I can't guarantee I'll read each and every message, but I will look at their subject lines. A glance, that's all I can promise. Is this okay? Great. Great. I am loving this. Will you deposit the $1 into my bank account every time I get a message, or once a month like eBay does?
I cannot think of a way that this couldn't work out well for me.
System checkpoint complete.
