Hi aa-wg, For some context, today and yesterday I have been receiving spam in the form of fake abuse notices to my abuse contact email address. Is there a generally accepted standard for when it's okay to block an address or a prefix from emailing your abuse contact? I consider being able to contact the abuse email address of a network a rather important function, so I prefer not to block it. But also as I have more relaxed spam filters for the abuse contact to make sure nothing gets lost, it feels like blocking the address/prefix is my only option other than manually filtering through these emails (10 so far in total, today and yesterday). So back to the question, is there a generally accepted point at which blocking an address/prefix is fine? Thanks, -Cynthia
