What's the point of asking a question (...does this make me a bad person for discriminating?) if you're not ready to accept some of the answers?

Yes, geoblocking totally makes the internet a shittier place. In the same way as the hackers and scriptkiddies make it the shittier place. It's a chicken and egg situation. You're blocking part of the world because it's dangerous waters. I am blocking part of the world because I disagree with the politics of that particular part. We are together making geo-blocking tolerable and acceptable. We're together making the internet more shitty than it deserves. Congratulations.

By the way, I'm not sure I wouldn't have done the same thing you did. I guess if I can't properly manage the security of a resource, the easiest way to deal with it would be to eliminate the source of the attack vector. I wouldn't deny that I'm part of the problem though. Because that's exactly what I am.
