That's fine.

There are probably a number of systems that feel that way. I only
meant to say that we've tried a "block-first" strategy w/ geocities
before and had to remove it. YMMV.

You should also know (may remember) that the blackhats experimented a
while ago with using several other hosting sites, including msn, and
seeding them in round-robin fashion so that they all appeared in each
campaign. Since this experiment stopped abruptly I doubt that it has
been abandoned - rather, it was put on the shelf for a while. At the
time it was clearly effective for them. I think it likely they will do
that again (don't know when) since they are putting some new effort
into this path. I don't have any evidence of it yet.

I discovered that on 20060503 the blackhats made some significant
changes to their use of geocities links and their transmission
patterns. I've re-tuned the F002 bot to compensate and it is currently
reviewing a handful of new geocities links every minute and adding
approximately 1.2 new rules per minute.

I suspect that the lull we observed may have had something to do with
their "tooling up" for this set of campaigns.
