It does archives already with the !archive
command: !archive https://gitea.elara.ws/Elara6331/lemmy-reply-bot. There's also a !paywall
command for removing paywalls.
I used to have it change Twitter links to Nitter but Nitter almost never works now with the API changes so I removed it. I might end up having to do the same with teddit/libreddit. Without a command, it currently handles YouTube, Imgur, Reddit, and Google AMP.
Yeah, Teddit and Libreddit are really unreliable after Reddit's api changes.
