Which definition of spam are you operating under? I think it is a fundamental trait of the actor.

So you would expect a spammer to only ever post spam, even on their own personal account? Or a spam emailer to never send a personal email?

I know sales bros who live their live by their ABCs - always be closing, but that's besides the point. if the person behind the spam bot one day wakes up and decides to do turn over a new leaf and something else with their life, they're not going to use the [email protected] email address they use for sending spam as the basis for their new persona. thus sending spam is inherit to the [email protected] identity that we see - of course there's a human being behind it, but as we'll never know them in ant other context, that is who they are to us.
