No.  It'd just increase a LOT, astronomically.
i suspect that, if we opened smtp relays again, unblocked 25 for
consumer chokeband, etc., total spam received would likely increase a
bit.  but my guess, and i mean guess, is that the limiting parameter
could well be how many bots the perps can get, not how well those
bots are blocked.

i keep hearing that, but am having a hard time finding supporting data.
