Signing in with Linked In

So I am facing this problem, I want to make a new account on FCC, but the problem is that there is no sign up like the old version, so I tried signing up with Facebook and Twitter but it didn’t work, so I signed in using LinkedIn and it took me to someone’s else profile who earned certificates and accomplished many items, that’s so weird.

Please take a look at the below image, I know this could be technical issue from the website itself, but I don’t know where else I can report to.

Now they text you a code.
