BATV on Gmane?

Gmane has been inundated by backscatter from spam lately. Someone
has been sending spam with <non-existant-address> <at> sea.gmane.org as
the MAIL FROM. These messages all end up in gmane.config, so they
don't really affect the mailing list archives per se, but they're all
handled by SpamAssassin etc, so they soak up resources.
So I'm thinking about starting to use BATV (which basically mangles
the MAIL FROM by using cryptography, but still leaving it valid) and
rejecting all bounce messages (i.e., from <>) at the MTA level.
Which will cut down on load and stuff.
A different approach would be to just drop any bounce messages, but
that's problematic as we wouldn't see bounce messages from the sign-up
process when we're sending subscription messages to the wrong
Or I could make the system not pass bounce messages through
SpamAssassin, and then file them in a special gmane.config.bounce
group. The problem here is still the same -- that group will be so
full of spam that it'll be impossible to catch "real" bounces...
Or I could do something else. Any ideas? I mean, this isn't a major
problem -- this is the exim queue length:
<URL: http://gmane.org/plot-queue.php>. So perhaps doing nothing in
(domestic pets only, the antidote for overdose, milk.)
