Yes, that's an issue, which is why we enforce it manually.  It's imperfect, 
but it's been reasonably reliable in the past.  We rarely have multiple 
members from the same company; if two users have the same IP routinely, 95% 
of the time they live together and will confirm that when we ask them.

"If nature has made any one thing less susceptible than all others of 
exclusive property, it is the action of the thinking power called an idea, 
which an individual may exclusively possess as long as he keeps it to 
himself; but the moment it is divulged, it forces itself into the possession 
of every one, and the receiver cannot dispossess himself of it."  -- Thomas
