Actually, what usually happens is that we have the person contact the Volunteer Response Team via email. They can then gather information privately, outside the public forums of talk pages, to confirm your identity.
And remember that this is done as a protective measure. It's just as easy for an imposter to create an account and claim to be the subject of an article as it is for the actual subject to create an account. That's why, unless OTRS has vetted the situation, we take a skeptical view to people who claim to be the subject of an article. (That said, an account claiming to be a more major celebrity, such as Lady Gaga, would be blocked until they'd contacted OTRS to confirm their identity.) —'''''' (talk)
