I personally prefer addresses that don't share any identifying information with each other, since those are easier to correlate. E.g. degen-channel5 and degen-baddragon could easily be correlated by somebody who happens to have both lists side by side, and based on the service, guess how to spam you in new and creative ways
My ideal setup is [random_characters]@[service], where there is zero correlation besides the fact I use the service to begin with. It doesn't look like port87 offers that, which is a real shame
