If you are seeing queries for this domain, than you are likely participating in DNS Amplification attacks and your DNS server is probably reachable from the internet and has recursion enabled.
If you are seeing responses for this domain.. unlucky. You are currently beeing DDOS-ed! Good luck.
IPtables:
There are two iptable rules available. If your distribution supports Iptables 'u32' module pick this one, otherwise use the 'string' rule.
U32:
iptables --insert INPUT -p udp --dport 53 -m u32 --u32 "0x28&0xFFDFDFDF=0x0a44444f && 0x2c&0xDFDFDFDF=0x53464f52 && 0x30&0xDFDFDFFF=0x554d5302 && 0x34&0xDFDFFF00=0x50570000" -j DROP -m comment --comment "DROP DNS Q ddosforums.pw"
More U32 rules can be found here:

String:
iptables --insert INPUT -p udp --dport 53 -m string --from 40 --to 55 --algo bm --hex-string '|0A64646f73666f72756d7302707700|' -j DROP -m comment --comment "DROP DNS Q ddosforums.pw"
