My reaction seems to be unique so far. I would think it much better
for the Wikipedia project that we do not publicise that we know
exactly who is doing this. It is fascinating to watch the congress
staffers at work. It is just a pity that shortly they will smarten up
and be doing this with proper accounts via different IPs.
If there have only been a thousand changes so far, most of which were
positive, this does not seem to be a "major" problem. Certainly not
compared to the information we're gleaning from this. So, by all
means, let's continue to revert the particularly obnoxious changes,
but asking them to "stop it" will simply make it invisible.
