I'm fine with a blogger posting something that hasn't been fully vetted. As long as they have multiple sources to cite, and they make it clear that there's no official confirmation from any parties involved.
In this case, it was one article, on a questionable site, with zero citations to backup the assertion. That's just silly, and shouldn't have been given any credence by anybody until it was given some verification.
I'm fine with journalists writing things without complete fact-checking, as long as they let you know that.
