It's a pain with all these fraudsters out there... Unless I'm sure of the site, I wouldn't submit my usual e-mail address - it's real easy to set up a hotmail address to use for these occations and subsequently discard when the spam starts arriving.

Also, for some reason, I'm never quite honest about age and address when registering. Even here on the trustworthy English Forum, I've supplied a sligthly photoshopped picture of myself in order to remain anonymous (in fact, my natural hair colour is blond, which sort of alters the impression somewhat).
