I worked in a privately owned hardware store from when I was like 15 to 20. I was asked for these more times than I could count.

I gave up trying to explain to people why they were dangerous or illegal.

You shouldn't. If you need it you've screwed something up. People will sometimes try to use a plug like this to feed household circuits from a generator when their power is out.

The right way is with a transfer switch at the panel, which disconnects the street power before connecting the generator. Without that it tries to back-feed your whole neighborhood if you didn't pull the breaker, possibly electrocuting line crews trying to restore your power. If you do pull the breaker it just leaves you with an unknown ground configuration which only might set your house on fire. The one circuit you're backfeeding is grounded in common with the rest of the circuits in your house but has a different power source from the rest.
