What value does the reputation calculation have of an IP that's sent 20 messages to us in the last 30 days? This isn't a computation problem... well, at least until we reach the point where we can run copies of every user and ask the copy whether they want a particular message or not. Of course, you can't run a full A-level simulation at that point, since then you couldn't erase it after or reset it, and over time it would drift from what the original wants. Brandon
