If you somehow manage to put a URL without a protocol like http into the database, the link on the profile page is wrong. You can see this at https://elm-lang.de/#developers/klaftertief. @klaftertief's profile has such a URL and the link on his profile page goes to https://elm-lang.de/klaftertief.de. (I guess the URL was automatically imported from his public GitHub profile data when creating the account).
