Losing trust in the LD rating system


I just took a look at the Day 1 analytics of our game and noticed, that the number of ratings we received is significantly higher than the download number on our itch.io page (2x). There are no team-external clones of the Github-Repo.
I assume that this means, that there are people, who rate games without even trying to download them. We don't have any comments or other hints that would indicate that something with our downloadpage is wrong.
I'm really shocked by the proportions of this (50% meaningful ratings). Did I overlook something or is this really an issue? Do you guys have any statistics on that from your last LD games? Sure, 11 ratings is not really a sufficient sample size and I will monitor this further, but at that percentage I suspect, that I will still see a large number of baseless ratings in the end.
