In this case the threats all seemed to be delivered in Hebrew, so it's plausible that those involved resided in Israel.

Yes, it seems likely.

I assume the author would have noted in his blog post if the Hebrew used in making the threats came across as non-native or non-fluent.

Machine translation is really good these days, but I still think there are some "tells" for a truly vernacular and local command of a language.
