In this case, Mike Isaac, the original writer, seems to have a good amount of domain expertise, as starting last week he has been posting frequently on Reddit in an official role, discussing/answering questions about his reporting on the site. (Also claims to have been a redditor for five years, presumably on some other account.)
Oddly, all of his official account's posts have been in the GamerGate subreddit.
