The TMG firewall’s Web Security features include the ability to block sites based on site category. The categories are driven by the Microsoft Reputation Services (MRS).

Want to know how a site is categorized by MRS?

Then check out the Microsoft Reputation Services Feedback and Error Reporting site over at:

https://www.microsoft.com/security/portal/mrs/defa...t.aspx

Make sure to check your own sites. If you find your site has been miscategorized, you have a chance to dispute your place on that page as well.

HTH,
