One thing I try and remind myself with dealing with Microsoft is that they have an extremely limited selection of uneditable boilerplates to work with in terms of replying to messages. So I often keep pushing even when they say things like “don’t qualify for mitigation” because I know that’s just the boilerplate they have to use. If I think there really is a good reason for mitigation (ie, I’m not trying to actually get a client to make a change) I write back and explain why I think it does qualify (briefly) and ask for mitigation. Sometimes I’ll even ask for escalation. > I hope that Microsoft starts providing some information about why IPs are > suddenly blocked, specially for IPs that have a long term reputation without > issues.
