depends on how badly they want to get back on that interweb-thing...and
how clueful they are (or can be made to be).  if the penalties for not
being clean are steep enough (no interweb privileges for a semester),
then i think they will do it right.

i would hope that you are filtering and rate-limiting upstream traffic,
and that you have built the server with sufficient horsepower and
self-preservation hooks that it would survive.  ftp or http don't require
too much upstream, and you probably don't need to allow much else from 
the users computers
