Quoting Brian Kelsay Brian.Kelsay@kcc.usda.gov:
Anything I have to give an email address for where I think I may get spam, I allow MS to take the spam.
I usually use maillinator.com or dodgeit.com for these types of things. I believe maillinator.com was first and some sites have stopped accepting email addresses from that domain because they know people are using it to skirt registrations.
But most sites don't block it... yet.
