Is it bad to give someone your iPhone udid for a IOS 7 beta?

Not bad at all. I gave mine to http://www.instantudid.com/ for $5, and they registered it instantly.

Not if you go through a legit site. I used http://www.ActivateMyiPhone.com/ and registered my UDID there. Used PayPal so I could get a refund if there were any issues, but all was good!

No it's not I did it with instant idid and got iOS 7 on my phone a few weeks ago, the reason they need your udid is so put your phone on a developer account so you can have access to the beta. Once they add you you download ios 7 from online(I got mine from frost wire) and then put it on your phone via itunes.
