Why does NW think domains like Adju//vent (com) are cash cows?

Adju//vent looks and sounds like a real word, but it’s not. It is very similar to Adjuvant, however, which is real. That’s kind of a million dollar word in science / medicine / biopharma. Can you actually get good money for these sorts of misspelled names? NW seems to think some are cash cows. Thanks.
