While DDOSing my pool, check out what this asshole sent me

So I run blisterpool.com (simple p2pool node + layer of bonuses), and this asshole decides to try to extort 2btc from me. My node has been under a ddos attack for about 2-3 hours now.
I get an email to all my addresses, and then finally a message on bitcointalk a few minutes ago. Copy/pasta of message:

Your mining server is extremely vulnerable to ddos attacks
I want to offer you info how to properly setup your protection, so that you can't be ddosed, at >least not with so little power. My price is 2 Bitcoin only.
Right now I'm running small (very small) attack which will not crash your server, but you should >notice it in logs. Just check it.
If I increase the attack size, I could completely crash, it would drop all connections and damage >would be big... Don't worry, I will not do it. Smiley
I want to offer you info on how I did it and what you have to do to prevent it. If interested pay me 2 BTC to 17aLGgw8AwJdqiBtMMG1QtQJgNQQkiyEsp
Thank you.
It's a shame for him that I can just shut the server down for a while and join one of the hundred other public p2pool nodes out there.
