The point is more about whether or not people should trust any password of any kind handed to them by a website they know nothing about.

Do you trust the password to be difficult to crack? Do you trust the website not to be handing out the same password to multiple people? Do you trust the website not to be passing the password to third parties? Do you trust the website not to be harvesting what it can about you and squirreling that away with your free password?

On a secondary level should we be following links to unknown websites in the first place and assuming they are working in our best interest?

The link to the site may be bona-fide, but I can't tell and I doubt anyone else can. It seems to be operating from Russia with the poster residing in the Ukraine.
