For me it's the fear of DNS/domain hijacking, theft and other things I don't know much about (the whole infrastructure). E-mail is central to my online identity and a dedicated attacker could make my life a living hell if he got hold of my domain, even if only by a few hours. That's the real scary stuff, getting your ip blacklisted is nothing compared to that. I know about https://news.ycombinator.com/item?id=15855081 https://news.ycombinator.com/item?id=15855081, ironically I'm not afraid of losing my Gmail the same way since it's impossible to talk to a Google-human.
