We ask that you be respectful of the people who host events on itch.io. People from our community put together jams so they can build their own communities of people who are interested about a common topic. Posting your projects in unrelated game jams not only breaks our rules but also hurts the hosts of these events.
I'm asking you to be more conscious about the jams you submit your projects to, do not submit to random jams just because you can. If you can agree to that then we can remove the limit on jam submissions from your account.
