According to this article [CNet News, in new window] a new start-up company has created a piece of software for ISP's. This software detects if a user is going to a known phishing site, and shows a warning, along with ads from Yahoo, and other sources.
So we are creating a good anti-phishing campaign with unsolicited advertising (spam). I don't know my stance on this yet, but why is every little bit of screen real-estate is being used for advertising.
There needs to be an Internet governing body for controlling the advertising on reputable sites. (Seen yahoo recently?)
