Checked the user's account. In lack of more info, it looks suspicious, as it only has a handful of posts, all article links, and no comments to show it's an actual human. Perhaps it is a bot grinding trust more slowly, to not be burned too quickly. Or maybe it's just an user that seldom logs in here.

And borrowing this comment to opinate on the article itself, it still sounds relevant as the technologies the article's OP proposes only got more powerful. Bet now we can even use LLMs to do that, no coding or research needed on the attacker's side.
