Please don't think of it as snitching.
Most people who joined the jam want to be able to have a fun and fair experience, so helping us moderate the jam by reporting games/people that are breaking the rules, or making the jam experience worse, is helping us make the jam closer to what people signed up for.
Thank you.
(There is a "report" button under comments, and above games inside of their jam page, that actually goes straight to the moderators, and not to itch. So if you report it through that button, you can report it to us without needing to make a public post for it. 👍)
