In that case you could have left out the "My god, what are we spreading here?" which seems overly dramatic to me.

You could also have substantiated "This is pure conspiracy theory through "news" sources that have highly dubious credentials." by expanding on what makes those news sources so dubious they deserve scare quotes, since not everyone will be familiar with them.

Attributing the actions of one user to the whole community as in "HN shouldn't be fueling this kind of unsubstantiated speculation." isn't great either.
