It's not an active account if by "active" they mean "generating content". While Twitter isn't a typical content aggreagation site like Youtube or Reddit, tweets are still "content" in the sense that they drive further user engagement on the site.

Words used to mean things. The current HN submission title just says active, heavily implying accounts with any kind of activity (eg. like, follow/unfollow), not "users who Tweet".

Sure, clickbait headlines are the norm and the devil lurks in the details, but still, many comments have been spent on this, because it's clearly misleading.

~80% of email is spam, it doesn't surprise anyone, because it's so cheap to send spam. Similarly it's easy to create fake accounts and spam, yet it doesn't mean much.

Who's counted as "engaged"? The people reading, or only the people writing? More to the point, if Twitter moved to a subscription model, would zero lurkers buy in?
