I made this tool some time ago to respond quicker to reports which didn’t federate to the instance of my main account (lemmy.world). Previously I would have to check from multiple instances daily, and now I get a notification on my phone when a report is made within a couple of minutes. I cleaned it up a little and added some documentation in case anyone else is dealing with this issue or needs something like this.
Do you still need accounts for all the other instances or can it work with just one account?
It depends, if report federation issues are a major concern then yes, if not, then you can do without.
I’ve had issues with reports being missed because one instance didn’t federate any of them to anywhere, so I’m using it with multiple accounts.
