Why do all of these mail services look like spam engines?

I know several companies that seems to shop for these mail services. Someone spams me though a service like this, I complain, next week I'm getting email from the same sender but through a different spam service.

You email/spam service providers need to create a clearing house for bad customers, because bad actors just move around and change names and always find a new home to land in.

I don't know about the acquiree but as a mail admin I've found Mailgun to be unresponsive to abuse emails and an unrepentant spammer. Block them and move on.
