Yes, this is precisely the theory I had as soon as I read the first several sentences. If you look at the list of sites, you'll see there are spam sites in there (ex: buzzll.com) that have diggs from the suspected accounts. If Digg is behind this, why digg random spam sites? Also, as dumb as Digg is, I have faith they could do a little better than d42, d43, .... etc. I think what we have here is a spammer testing ways of gaming the system, or proceeding with gaming the system.
