Ah, the joys of the Internet. You can't get the information you need until you give the annoying website your email address and then verify the address by clicking a link they send you. But once you do that...it's spam for breakfast, lunch and dinner for the rest of your life.
But there's hope. You can get a disposable email address for free. You don't even have to do anything...just make up whatever temproary email address you like. Mailinator provides just such a free service for throw-away email addresses. Just type in anything at all, followed by @mailinator.com. That's your disposable email address.
For instance, I could be email@example.com or firstname.lastname@example.org or email@example.com or any other email name I desire. Then...just visit mailinator.com, type in the made-up address, and voila...there's the message with the verification link. The "account" disappears in a day or so and you'll never have to see any spam sent to that address ever in your whole life.
Ah, the joys of the Internet.
