So does a broken clock twice per day. Of course if we assume the worst about someone and their intentions we'll be right some of the time.

The collateral damage, of course, being that the internet gets shittier and more negative in general as a result.

This one interaction does not change the general rule...getting sufficient evidence before drawing conclusions leads to better decisions.

Far too many people take a hint or a shred and call it sufficient evidence. I am suggesting a higher threshold.
