I know when someone asks me for an address, I do one of three things:
1. Give it, because I "know" the requestor.
2. Ask the person whose address is requested if they mind if I release it. (when I don't know the requestor well)
3. Tell the requestor to fuck off.....if they are completely unknown or an asshat or otherwise questionable.

Now, if we are going to limit access to any such list, perhaps it's workable. I do know, however, that there are a few guys on here I would never consider giving out their address....except to the most trusted of members. And I have no doubt that is the way they would want it.
