multiple 1 star
You might want to contact Itch support, if you suspect harrassment.
Other than that, this is not unusual: being able to rate things that you did not buy. On platforms with public reviews you usually see something like a verified purchase or something, but the unverified reviews still exist there.
On Itch specifically, you can buy without having an account. In generall, you could know the game from some place else. But a new game and multiple 1 stars sounds odd.
Many people complain about reviews not being attached to the games. They would like to see their reviews.
I can imagine several reasons why this is not so on Itch. But if they were public, they should also have this verified purchase icon.
But for pay-what-you-want games, I doubt that it would be usefull to have your proposed differenciation between ratings of customers and other ratings. There is bound to be heavy bias.
To be honest, having ratings at all is a big deal alreay. Most people do not rate the games they play. Only if they care. And this happens usually if they like it very much or are disturbed or angry about something.
So for few ratings the bias would be even bigger and for many ratings it does not matter, because it evens out.
I already reported the reviews in question nearly a month ago when I made this post, but Itch staff never removed the multiple 1 star reviews from people who had no way of having played the game.
Had to result to just turning off reviews due to harassment Itch won't do anything about, as the game had 0 downloads and several 1 star reviews.
