Thanks for the reply.
I've already checked the documentation, including the Indexing FAQ, Search & Browse FAQ, the “Try My Game” scam post, and multiple older threads about similar cases many times.
The system doesn’t provide any notification when a project is quarantined or deindexed, and in many of those threads developers mention waiting weeks or even months without receiving a response from support.
In several cases, the only activity happened after someone posted publicly here.
So it's difficult for us to understand what triggered this or how to resolve it on our end to avoid on future projects.
We really appreciate you forwarding this to the admins and taking the time to help.
