Don't worry, once you're on one of the naughty lists, it's going to spread by itself. Your domain will never be off of all lists simultaneously, it goes around and you can keep chasing it if it's your domain but you'll never convince everyone before another has copied it again

Most vendors of such lists don't have a contact method, don't respond, or say they're only aggregating a set of secret sources and it's up to me to look for those. Only a handful will actually respond to requests to re-evaluate the allegation, and remove you if it was/is false
