Unable to block a person in xfire

[choobinator]

As the topic says, i can't block this person in xfire,
i can block other users from my list, but i can't block the person
i want blocked... what i tried to do to fix this?
uninstalled xfire, removed it completely from my HD & deleted
in my registry, re-downloaded & re-installed xfire, tried to
add him to my blocked users list.. it says he is blocked,
then he just logs off & on, and he is unblocked....
And if i block him, and i logoff/shutdown xfire & then log back in
it doesnt show he is blocked anymore.... how is this possible? -_-"

You cannot block your friends. You must first delete the user, then add him to the block list.

I've deleted people from my list and then added them to the block list and they can still try to add me and view my profile.
