Most of the time, I don't review a game at all if it sucks. I delete it, wipe the space in my brain that remembers most of it beyond just enough specifics to avoid it in the future if it ends up getting updates, and move on. So my ratings tend to heavily favor giving games 4-5 stars rather than giving games 1 star. I don't know if this is common practice among players, but I'd guess that it isn't uncommon.
As such, I think it's important for people to be able to give 1 star reviews if only because a shitty game they got for free made that much of an impression on them. If their review as a result is low-effort and/or breaks the rules because they had an issue with a tag or something else stupid, report their review. It's not hard to do. But if they had legitimate problems with your game and just happen to think it deserved 1 star, then players should have the right to have their opinion heard in the review section for your game so others can consider what they had to say.
In almost all cases, f95 should preference the players' needs over the devs,' which means that we should tend toward not pruning reviews solely because they're 1 star. This is, as ever, a porn game piracy site rather than a porn game advertisement site.
