Tim-
Would there be any objections to systematically blocking all anonymous proxies on a site-wide basis?
Yes, from me. We need knowledgeable people in countries like China to be able to write about the facts without fear of ending up in a labor camp. Of course we do not allow original research -- but we do allow NPOV contributions from anyone, and blocking all anonymizers threatens to lock out certain persons from editing.
I know that these anon proxies are annoying. But I would prefer if we continued our curent whack-a-mole game in the interest of freedom of speech. Most sock puppet users don't know about anonymizers anyway.
Let's implement ways to filter out vandalism more effectively instead. The login box on the edit screen is also a good idea.

Erik
