Oh God, those people don't even deserve your attention. If they were offering a constructive critisism, it would have been one thing. But those guys are clearly trolls. You reported them - perfect! Sit back and forget about them.
Medium is awesome, because it requires a paid membership. Sad people who enjoy putting others down to feel better about themselves are less likely to spend money subscribing to a paid platform. So, we don't see too many trolls here.
Don't waste your time thinking about folks like that. There are many more nice people who deserve your attention.
