There are a couple tricks that might work, but none are moderately
reliable.

"Offline messaging" vs "Off the record" combine together to yield one
possible bug.

If the recipient is truly off-line, you get an error that the message
can't be delivered or off-the-record mode can't be used or something,
but if the recipient is online but invisible, it doesn't return the same
error.

I vaguely recall that the same trick worked for blocked vs off-line, but
this isn't a particular subtle method as the recipient gets messages
about off the record mode.

Alternatively any site claiming to do such a test could be a phishing
scam, there were a couple sites phishing for MSN credentials once upon a
time, they'd claim they needed your username and password to check your
contacts to see if you were blocked or not.

I stand by my initial answer, if you want to know, act like an adult and
ask the person.
