The easiest way to avoid bad listings (including stupid ones like those you mention and sketchy ones from terrible sellers) is to change your Search from the default Best Match or the popular Lowest Price (plus shipping) to Highest Price Plus Shipping.
It's counter-intuitive, but those garbage listings do tend to be very cheap and poorly made items, if they exist at all, and you can drill down from the highest price to your budget level more quickly than you can slog through the trash.
And of course, the seller does not speak or read the badly translated language and does not know that the translation is risible.
A friend was posting about flooding in Quebec and showed a newspaper headline, which had been automatically translated as "The river is nagging. We can hear it from the house." The actual word used was "grondait", which would have been better translated as "growling" or even "roaring".
