Took me like 7minutes to tag a webp conversion.

If you are speaking about the people publishing this on Danbooru, then fair.
If you are speaking about MentalEdge, then you underestimate the time this would accumulate if done for every of their daily posts. As an example I spend over 5 hours a month (approximate guess, as I do it in big batch sessions and the last one was last month, so I can't remember well) searching for images and processing them into posts. And most of the processing (lookup of title, tags, artist socials, composing the body text) is already done by automated software.
