In any other context, “monitoring intake” implies that the monitored party is consuming a quantity of the thing under discussion, and that the monitoring party is getting a report on what, when, and how much.
You wouldn’t say “monitoring food intake” about someone abstaining from food, or “monitoring alcohol intake” about someone maintaining sobriety. You’d probably say “fasting” or “avoiding alcohol”, or similar language. Such language should have been used here for clarity, IMO.
People on the thread are responding like they are reviewing each other’s porn, because the language encourages that misinterpretation.
