I have my contact form set up to throw an exception when a spam attempt is made so now instead of receiving a spam, I receive an exception report.
It's always the same two IPs:Code XML:Exception information: Exception type: System.Web.HttpRequestValidationException Exception message: A potentially dangerous Request.Form value was detected from the client (message="com1, <a href="http://prof..."). Request information: Request path: /Contact User host address: 18.104.22.168 User: Is authenticated: False Authentication Type: Thread account name: NT AUTHORITY\NETWORK SERVICE
User host address: 22.214.171.124
User host address: 126.96.36.199
I'm on shared hosting and don't have access to IIS control panel. Can I block these IPs without affecting performance for non-spammers?
