Very cool script, here's a quick python3 translation for others:

from scapy.all import IP, DNS, sniff
import ifaddr
import subprocess

bad_sites = [
    "reddit.com",
    "youtube.com",
    "news.ycombinator.com",
    "wsj.com",
    "theintercept.com",
    "facebook.com",
    "twitter.com",
]


def check_match(dns_name):
    # just so it's eaiser to add domains
    if dns_name.startswith(b"www."):
        dns_name = dns_name[4:]

    # if it's a bad domain, let's shock the user
    if dns_name in bad_sites:
        print("%s is a bad domain" % dns_name)
        subprocess.run("play -n synth .5 sin 1500".split())


def get_adapter_name():
    # get the first available adapter
    adapters = ifaddr.get_adapters()
    for adapter in adapters:
        if len(adapter.ips) > 0 and adapter.ips[0].ip != "127.0.0.1":
            return adapter.name


# listen for dns requests
def querysniff(pkt):
    if IP in pkt:
        if pkt.haslayer(DNS) and pkt.getlayer(DNS).qr == 0:
            check_match(pkt.getlayer(DNS).qd.qname[:-1])


interface = get_adapter_name()
print("using interface: %s" % interface)
sniff(iface=interface, filter="port 53", prn=querysniff, store=0)
