You may change message in language file for instant change to something else like 'Page is not available'

Yeah, but unlike Facebook I want to give a better user experience, maybe you can discuss if my idea is useful?

And can you at least fix the wrong message, please? :)

If you block someone it defeats the purpose of block if you want to visit his profile.

Just like Facebook you can unlock from profile settings page

Oh yeah, my fault

But 2 things:

When I block someone and try to visit his profile, it says that I have been blocked by this user but I blocked him, so that’s a wrong message

And:

If you block someone, you should be able to unblock him when you try to visit his profile, better user experience :)

Not true profile must be blocked. Did you trired to view using non admin account?
