A question is not a leading/suggestive question just because it "leads the comment". Parent was merely picking up the grandparent's main claim (https://en.wikipedia.org/wiki/Leading_question also doesn't define the term by whether it can be answered plainly or not either).

That said "something being unfortunate" is a very subjective thing connected to personal morals. Intuitively I don't have much empathy for "victims" of (not outright criminal (by which I mean heavy scamming and the sort)) trolling either, it's the natural rule of this place. You'll get bitten by it a couple of times and move on. Nothing to see here.
