IPWORLDNET is that big blue molar tooth in the graph on the right.
In the
interactive chart
you can see IPWORLDNET's Autonomous System (AS) 19875
winning the month with two bursts of spam,
and then dropping almost to zero.

That's not the only spamming churn activity in Canada for October. The log chart shows MetroBridge Networks Corporation AS 25976 METROBRIDGE-NET jumping up from zero to take ninth place. It looks like one organization may have cleaned up its act while another got infested.

Last month's winner, Canaca-com's AS 33139 CANACA-210, came in
second. From there down it's mostly the usual suspects in slightly
different orders.
Interestingly, longterm winner Bell Canada's AS 577 BACOM
only came in fourth.
This is unusual for a national telco.
Maybe they're watching the rankings?
