Twitter Verifying Accounts

And what are they going to do when you just happen to have the same name as a well known person?

Stop you from using your own name?

This is what they are doing.

"With this feature, you can easily see which accounts we know are 'real' and authentic. That means we've been in contact with the person or entity the account is representing and verified that it is approved. (This does not mean we have verified who, exactly, is writing the tweets.)

This also does not mean that accounts without the 'Verified Account' badge are fake. The vast majority of accounts on the system are not impersonators, and we don't have the ability to check 100% of them. For now, we've only verified a handful of accounts to help with cases of mistaken identity or impersonation."
