the rules are simple. if you are listed on the Umbrellix DNSBL, you probably done fucked up good.

response code meaning
127.0.0.2 made credible DDoS threat against an Umbrellix user
127.0.0.3 “and respected, in some circles, democrat, said we wanted to get rid of our second amendment, in other words, get rid of it. that's, tyah, we're gonna protect our second amendment…” “we'll be/we are setting records” “supreme court judge, fantastic justice gorsuch” (severely garbled English in the context of violations of the moral code)

use it for whatever you want. it's dnsbl.umbrellix.net. have fun.
