This is a major problem with this platform. The ease of which you can just create an account in someone else's likening is crazy. I know that it would be hard to make this harder for people to do but efforts need to be taken.
I think an introductory post with a picture is almost a necessity. You don't have to give out your full name or whatever but knowing that there's a real human willing to show their face is a good start.
Trying to stop people imitating real people though is a whole other kettle of fish.
