I'm a game dev myself, but I enjoy playing other games. I rate them as well.

But, on games that are bad or trashy, I give them a 1-3 stars (as you do). The thing is, is that people are coming to me and giving my game a bad rating because I rated another game badly. I can confirm it since it's commented on my page before the rating. So. My question is: How are these people seeing my rating? I don't leave a comment with it, so I don't know how they know.

You can also disable ratings/reviews for your game, which may seem like overkill, but it seems to me on itch.io they're not very visible anyway and I'd rather people post on my discussion boards.
