Yes, the exponential growth is suspicious.

I've been trying to find a relationship with other lists, but it is rather
difficult (without proper statistical analysis and some adjustments to the
POV.)
The only other announcements lists I think I missed are:
http://lists.debian.org/stats/debian-devel-announce.png
http://lists.debian.org/stats/debian-security-announce.png
They could in fact demonstrate that it was just a cleanup (actually, it
would be easier if somebody from the listsmasters team shed some light
here.) It is common for moderated, announce-only, lists to accumulate
bouncing addresses because often those sending the announcements are only
those who receive the bounces.

Number of subscribers didn't drop, much, but the traffic _did_ drop (less
flamewars? :)
: http://lists.debian.org/stats/debian-security.png
Except for the two big events, the traffic and subscribers did drop; but the
number of subscribers increased again.

This one is very interesting, as it is the main contact point from our
users. The number of subscribers did not drop, but the traffic did (non
surprisingly, the number of subscribers increases when the traffic
decreases, and vice-versa.)
I'm not drawing a conclusion, that's left to the reader.
