Comments made but requires log in.

Maybe I don’t understand the whole system but..

I have comments on BUT you must be registered and then logged in.
So if you hit “comment” it asks you to log in. Of course no one BUT ME can since there are no other registered users. I assume the only way to register is if i register the user myself.

So how did I receive a comment like the following:(I replaced my website with “domain”

… [Trackback]…

[…] Read More: domain.com/?p=1714 […]…

Is that not actually a comment.

I just want to make sure I didn’t get hacked or anything like that or have any security problems.
