Yes.  The CMU Tor exit started with the reduced exit policy, and we
wound up additionally removing access to ports 22 and 23 (that is, ssh
and telnet) due to continual portscanning attempts.  And I mean
*continual* - multiple scans an hour, 24x7x365 if we'd let it go on.

Campus IT has also noticed a couple of attempts to scan port 3389
(Windows RDP) but that happens much less often.
