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.

• Throughout the rest of 2014, DD4BC attacked various Bitcoin mining pools, Bitcoin exchanges, Bitcoin wallet providers, etc., mostly in Europe and North America. • Most/all targets were Bitcoin-savvy. • Extortion demands have ranged from 1 – 100 Bitcoins: approximately $227USD - $22,700USD.

If you are a Scandinavian company using a centralized service for any of your business needs, you may be faced with a threat from DD4BC in the very near future. A string of incidents involving DD4BC last year culminated with the creation of a 100 BTC bounty [8] after the group targeted bitcoin exchange and wallet service Bitalo [9]. This amount swelled to 110 BTC following a contribution by AntPool operator Bitmain during the mining pool attacks. Bitcoin cyber criminals by the name of "DD4BC" have plotted to launch cyber attacks against some of our biggest financial institutions, including Westpac and Macquarie Bank. Source: Akamai. The exploits of DD4BC go back at least a year. In November of 2014, reports emerged of the group having sent a note to the Bitalo Bitcoin exchange demanding 1 Bitcoin in return for helping the site enhance its protection against DDoS attacks. At the same time, DD4BC executed a small-scale attack to demonstrate the exchange’s vulnerability to this method of disruption.
