I have no way of knowing, and as explained in lots and lots of topics, itch.io staff seldom explain their decisions.

The moderator is not an employee of yours or Itch; he is a volunteer moderator for the community. The most he can do is inform the administrator about your ticket. And for your information, the administrator does not provide feedback to the moderator, so they have no way of knowing the status of your ticket or why your jam not appearing on the calendar.

If you want to contact the staff, the only official way is to contact support. Threatening the moderator with a barrage of emails is completely useless, because the moderator doesn't work for Itch and doesn't have access to support tools. And he's not lying when he says he'll inform the admins about your ticket. The problem is, the staff doesn't change their decisions based on what the moderator tells them; it only serves to draw their attention to your case.

PD:  I also want to let you know that the forum is not answered by the staff and is not a way to contact them. As I mentioned above, the only official way to contact them is through the support email.

Get help from the itch.io community. Have a quick question or issue, other members of the community can assist you in finding an answer. If you need to specifically contact itch.io staff you can message our support team.

Strange. Below is what the page looks like on my side. I flipped my browser’s dark/light mode, mobile/desktop mode, and my device color temperature to check for significant differences. This was the color scheme each time.

No, actually, this is embarrassing. There was another layer of dark mode I missed.
