Things to think about before you call someone "Bad"

[Bourne_Endeavor]

It comes off as hostile though. The 90 question marks are not needed. You are already setting the grounds for bad things to happen in that run. If for whatever reason, the healer makes another mistake, what are you going to do, add 1 question mark to your already 90? Most likely a recrimination or two are going to slip, and from there it all goes downhill. The underperformer won't learn a thing, and the only thing you'll manage for them to obtain in that run is a bitter experience.

While debatable, even taken at face value, you're equating hostility with harassment. Those are vastly different things. Does it become less hostile if they type a single question mark? Putting all that aside, who made you the arbiter of player etiquette? People are allowed to express their annoyance. Now if they continuously heckle this hypothetical healer, you'd have a point. If done once? It's nothing. It certainly isn't harassment by any stretch of the definition. You're essentially demanded a safe space where people voice absolutely nothing except praise or remain silent lest they hurt someone's feelings. A potentially rude comment does not constitute harassment.
