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:
DD4BC Newbie * Online Online

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.

Cyber Criminals Targeting Financial Institutions Your Bitcoins or Your Site: An Analysis of the DDoS for Bitcoins (DD4BC) DDoS Extortion Campaign.

Also read: Developer Creates Solution for Bitcoin Ransomware. DD4BC – Notorious Gang of Bitcoin Extortionists. 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. An example of such activity is the criminal group DD4BC — DDoS for Bitcoin — whose members were arrested by Europol in January 2016. Hackers blackmailed online casinos and then moved on to attack financial institutions in Switzerland, New Zealand and Australia. 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. • 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. 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.
