And this is just the tip of the iceberg. As described in the article, you can avoid this by hiding your "last seen" status.

But why use the "last seen" feature, if WhatsApp also has an "online" indicator? Funnily enough, that one can't be disabled and is visible to everyone! That has been criticized for over 5 years now, with no reaction from whatsapp/FB.

There was even a similar tool back in 2016 which used this "online" indicator instead, called WhatsSpy [0]. It's no longer maintained, but you can see screenshots of it on this old German article [1] or you might be able to find English articles as well.

I don't know of any current tool which does this, but I'd guess there are a few out there, since it's so easy to do and can't be prevented.
