I'm creating a forums based site and want to block the members that post spam or abuse. I was thinking about using an HTTPModule to do this but I came across the Dynamic IP Restrictions extension to IIS7. I wonder if it's possible to add IPs dynamically from my app to the extension?
Also, if you have experience with that extension this will be great. I'm esp. interested to know whether it can affect performance in a high traffic website.
Thanks
