I don't know how well this works but I know https://dht.chylex.com/ <-- this is a viable option.What should I even archive? A lot of this just spans over several months. I can start with the person that was bashed on in the new update. So I'll go ahead and screenshot as much as it as I can.
Sorry for doubleposting (meowthkip when you're online can you merge this and my other post together?) but there's also this tool which I've used (https://www.tyrrrz.me/Projects/DiscordChatExporter) and it works pretty well :0
