There was no backpeddling. Nothing you've said or pointed out changes that using a throwaway email address makes the information they get useless for identity theft.
A throwaway email address has no impact on the value of the physical, real world address data, it is irrelevant because the real world data does not change often.
The physical address remains the same and it remains a vector for ID theft to anyone creative enough to exploit it. Notice I said "vector" as in one piece of information, not everything. You say you should mock me but your lack of imagination to figure out how it is done is mockable.
Caution isn't paranoia and my point is that you are giving away your address details because you might win a prize. That doesn't change the fact that that information remains a vector for id theft when your original point was about email addresses.
If you don't think it's that bad releasing that information then include your real name, address and the other details in your response with a disposable email address and I'll show you what I can do with that information. I'll guarantee you might win a prize from supplying me with your real name and address.
