We're trying to be proactive on identity theft. A picture with steemit and the date would work. Sorry for the inconvenience.
In order to prevent identity theft we like to encourage users that have an online identity, post for a website or blog, and celebrities of all notoriety to verify themselves. Verified users tend to receive a better reception from the community.
Verification can be as simple as posting to your website or blog. If you use twitter or facebook, you can also create a tweet or post there. For our easily recognizable Steemians, a photo with you holding a piece of paper with the time & date will suffice.
Thank You! ☙
