I tried it today (just minutes ago 7:30 UTC):

toon at super:~$ ssh member at j3-fortran.org
Public key c8:ab:f4:85:26:e6:4b:33:ef:e7:d1:02:11:08:e3:90 blacklisted

IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
65:b9:a3:a9:d3:7c:59:d9:4f:7a:dc:81:24:bf:fe:fb.
Please contact your system administrator.
Add correct host key in /home/toon/.ssh/known_hosts to get rid of this 
message.

So it seems to work.
