Hi, IP Blocking based on country allocation is the worst you can do. Picture this: your customer is on a business tripp in India and it is not possible to access resources due to his then Indian IP. I made the same experiences with my Bank Account in the US. At present I am located in Europe and I am not able to access the Banks webpage (and the Web-Banking) due to this horrible IP blocking based on Countries.

To reduce spam we are planning to propose them a solution to filter traffic by country. We can add IP Blocks for USA and UK as a whitelist and allow only incoming access to those IP Blocks,everything else is blocked. Has anyone implemented this change on their production networks?Has it been effective to reduce spam?
