I oppose, there's the possiblity to block outside referrals as it  
happened
often enough in the past. Blocking ebay, google, aol, gmx and the bigger
mail-hoster would help enough. A list of commonly used hosters could be
genereated of the user-tables (for the case everybody is to lazy to do
this by hand)

A more technical solution would be to filter those referring from  
outside and
add a short text like "released under the GFDL" or the original URL  
(which I'd
prefer because licenses differ too much).

My last suggestion is to store informations about outside referrals  
(and hide those
from the search engines of course), maybe as admin page with a TOP10  
of the last 24h.

And finally a good reason about moving all to commons: Localized  
graphics are
only usefull for a single Wikipedia and thus are best kept in this  
single Wikipedia.
