The direction in which this thread went, shows that not everyone knows that it is not a good idea to use the same passwords on different forums. It is obvious that this mantra should be repeated everywhere and always, like the one "Not your keys, not your coins". No matter how many times it is repeated, there will be those who make such a mistake again.
Of course they know, they just don't care. And even if they use different passwords, chances are they're very alike anyway. Password1234 and Password4321 for instance. It would be more useful to promote a password manager, because most people have more accounts than they can remember.And even if they use different passwords, chances are they forget which one belongs to which site. To enter, they "try" all passwords they know, thereby compromising all of them
