How to weed out moderators and search bots?

Question

PHP

I do arbitration. The question arose, how to calculate when the user enters the page, and when the search bot or bot from moderation? There were thoughts to check for UserAgent, but anyone can substitute it, you can check for the presence of a loaded js script, if it's a bot, then as a rule js does not work (no mouse movement), and indeed what are the ways to separate "non-human actions" from real people ?

Answer 1

so the moderators are real people.
plus PS bots also use browsers (with js) sometimes.
so various shitty redirects and content substitution are now, thank God, quickly cut off.
