I can't recall having seen an significant increase in general terms
recently. The trend seem to go up all through the year:
You can also keep an eye on http://www.barracudacentral.org/data/spam to
see the combineed statistics of quite a few anti-spam boxes.
The only difference is that the old "me at example.com" to "me at example.com"
junk is back in force during the last few months.
I guess either 1 or more botnet(s) changed tactics or a new one emerged.
But most RBL's will kill of most of these attempts anyway so you can get
rid of them at the MTA level.
