Hiding a message like that creates the impression that the person actually did something to warrant it, besides disagreeing with a technical issue, or pointing out some misrepresentation, as I tried to with this message,
so that many people will not see it, and will end up with a negative impression of the author, without checking the facts for themselves.
I hadn’t ever used that feature before (just earned my Discourse “First Link” badge!), I’ll do that in the future!
