Many users no longer want to do this after facing a deluge of low-quality, low-effort games and having to rate them all. They'd rather let the dreck remain unrated.

Anyone who attempts to reframe this as "AI is not a contributing factor" needs to remember that in the past, the number of sloppy games were negligible due to a natural filter/barrier of entry where the indie author had to know how to code, or motivated enough pay someone who does.

AI lowers the barrier to entry - including for scammers.
