Associate accounts with websites

[jorgesumle]

Right now people can prove that they are who they are by linking some social networks. However, we cannot do that with websites.

I'm thinking about implementing a validation mechanism (like uploading a file to the root of the server and making Liberapay check for it), so that people cannot impersonate teams or individuals by claiming the ownership of websites. Using this feature we could link the Liberapay account with liberapay.com, and projects or bloggers could link their accounts with their websites.

What do you think? Can we do also something for people who don't have access to the server root, like people who use noblogs.org or wordpress.com?
