They didn't. They still don't. Only the piefed reports are making it through.

The way lemmy handles reports means that when a report is made, it goes to 3 instances at most.

When someone makes a report, the report goes to 3 instances. The instance hosting the account making the report. The instance hosting the community in which the content was posted. The instance hosting the user who generated the reported content.

The only people who can see these reports are admins of these instances, and any community moderators that happen to have an account on one of those instances. A community moderator or admin on any other instance, will not see the report.

As an aside, each instance only gets a single report, and if it's actioned by an admin or a mod, it closes the report on that instance (but not the other two).

As another aside, removals by admins on the reporting users instance and the reported users instance do not federate. These removals are instance specific. However, removals made by a community moderator (on any instance, whether or not it received a report) will federate that removal out to all other instances that received the content from the community.

Piefed federates reports differently. I don't know whether they send reports to everyone, or just to instances with community moderators, but either way, it gets past the current gap that lemmy has, where sometimes community moderators simply don't see the reports.

From federated user to the community's local instance, yes. From the community's local instance to federate) mod accounts, no.

They're apparently still not except from Piefed. (Thanks PoVoq for clearing that up).
