You are right, sadly we're not dealing with the most intelligent tech savvy people.
Yet being cautious and aware that these types of site exist and perhaps seeing how they operate - might help in prevention...
Unfortunately there is a small number of users who refuse to read anything until it's too late. Until something like WebAuthn comes to Darknet (which is unlikely for a number of reasons and the need for a physical device has it's own problems) there will be no real solution to phishing. Solutions like TOTP work to a degree but they are useless against proxies.
Honestly being phished on DrugHub or Archetyp you need to be braindead to say the least.
