Ben Edelman and Wesley Brandi have released a tool to help affiliates and merchants determine the level of fraudulent activity associated with specific merchant domains. The tool allows you to input a merchant's domain and it provides data on the number of cookie-stuffing, typo-squatting and spyware/Adware instances reported by their automated testing systems.

Here's Ben's overview of the tool: Search My Logs of Affiliate Fraud; and here's a direct link to the tool itself: Affiliate Fraud Information Lookup.

Try keying in some of your favorite merchants, you may be surprised by the results; then again, you may not. But remember, this is just data, how you use it is up to you.
