This DNS likely participates in DoS attacks. Attackers craft queries with a maximum amplification factor and offer up the victim's IP as the query IP. This results in bandwidth from the attacker getting multiplied by amplification factor and the attackers IP is hidden from the victim. Rate limiting, blocking abusive IPs, and blocking large transfers like zone transfers can help.
