I don't doubt it, but I think what's really happening is that they're getting rid of spam reviews by people who don't actually own the game and just leaving negative feedback for culture war purposes.
A lot of outrage over Kill the Justice League. Just imagine how much better life would be if young people could get this spun up over real problems like, you know, genocide or gas prices.
Honest question because I have no clue but I am curious. Do reviews stay when you refund a game on steam?
Yes.
