What type of bans are you seeing imported? Theres community and instance bans. It makes sense for instance A to import Instance Bs hosted communities banlist, but it would be wild if its importing instance level to then ban from both instances

I didn't ban anyone on my instance, it's a new one. They appear on this screen and in the modlog, it doesn't say anything about the type of ban
I think i recognize one of the names, that person posted CSAM
Itβs not clear but if you run an instance you just have a giant ban list in your admin page. No details about them.
If someone was abusing it they'd rapidly get defederated.
But that's a manual process. It would be nice to monitor the federation status of all servers and slap an algorithm like K-Means on that to find clusters and outliers.
You could then decide which ones to autonatically federate/defederate based on that data.
I'm going to look into that, maybe I can write the part that gathers the data.
Anything that makes Lemmy's "immune response" quicker has to be a plus.
It's a manual action, that must be taken for all instances AFAIK. An attacking software could pretend to be thousands of new instances, and a DDOS attack against lemmy is something that already happened in the past.
Been wondering this myself. Just didnβt want to say it out loud and give someone an idea hah
I was a bit conflicted about asking that too. I guess for anyone actively searching for vulnerabilities to attack that will be obvious enough
