I just read some news: a “rogue” ISP is taken down.
This ISP is McColo. Looks like it was helping too much spammers, the government and security researchers are so angry that they decide to knock it offline.
In the report there is a chart showing the amount of spam everyday. One can easily see that when the time the ISP was taken down, the amount decreased significantly.
Before I saw this I thought there is not too much incentive for an ISP to help hampering spams. It requires significant resources and can’t see immediate return. Now I see that right things must be done, always.
