Chronicle the life and tale of the fediverse (+ matrix)
Largely a sublemmy about capturing drama, from fediverse spanning drama to just lemmy drama.
Includes lore like how a instance got it's name, how an instance got defederated, how an admin got doxxed, fedihistory etc
(New) This sub's intentions is to an archive/newspaper, as in preferably don't get into fights with each other or the ppl featured in the drama

I'm a bit confused, how does locking down a single community help?
Are the spammers really just focusing on one community instead of switching to the next after it gets banned?
I do hope there is an IP ban option, so someone can't just use the same IP again to create an account on another instance and post CSAM from there. Obviously I do know about VPNs, but it makes it a tiny bit more difficult to spam in large amounts.
Most people don't have static IP addresses, so banning their IP will only stop them temporarily. Then whoever gets that dynamic IP address next will be banned too. Then there's CGNAT where 1 IP address can have up to 128 people using it at once and the address changes even more frequently.
We're talking about temporary bans here, which do work against spam. Private users do have dynamic IPs, but at home I think I've had the same IP for years. They don't wildly switch them around.
On second thought the IP is probably not federated though, so if there isn't a common IP block list which instances subscribe to it won't work.
Every time my router restarts I get a fresh wan IP. I can also manually grab a new one via the DHCP release/renew functions in it's config page.
Lucky you. My ISP grants a new IP every 6 months or so. Even charges extra to keep it static -.-
Weird, are you 100% sure? I can restart my router all day, my ISP gives me the same IP back pretty much every time.
Probably depends on the ISP.
What about IP + MAC Address?
MAC address is a Level 2 addressing system (OSI model) and will not leave the local network / stay within the broadcast domain. The web browser will not expose this kind of information to a web server.
Gotcha thanks for the clarification
MAC address isn't something a remote server knows about a client. Only the IP you should respond to is provided.
Ahh, I see. Thank you
