I guess OP thinks that vanity-eth.tk is a website with server side code.
If that were the case, the security of the private key would be compromised. But the website is client side only.
Or maybe the complaint is that non tech savvy users
might be getting confused and might be too trustful to other sites that do private key handling server side.
