For screenshots
MAKE SURE YOU ARE ON AN ALT.
Do NOT take screenshots on your main account.
Do NOT copy links from your main account. Always try to avoid using a site's function for linking, as it will make a connection between your account, and whoever clicks on that link. (If you have ever noticed YT videos with "si=" in them, that's what that is. Just copy links from your searchbar.)
GhostArchive/
Archive.fo are your friends. These two sites should cover nearly every single site you ever want to archive.
Archive.org should be avoided. Your cow can submit a simple takedown request and it will be gone. If what you wanted to archive is only available through Archive.org, use GhostArchive/Archive.fo to archive that Archive.org link.
cnvmp3 is what I use to download YouTube/Tiktok/Reddit/Instagram/Facebook/Twitch/Xitter videos as mp4/mp3, Null recommends
ytdlp. You might be too retarded to use ytdlp though, don't worry, I am too. The problem with cnvmp3 is that it has a limit for what you can download. Iirc it is 1 hour for mp4s, 1h30m for mp3s, and you can not download age restricted videos with cnvmp3. You can download age restricted videos with ytdlp after some fuckery in it's settings.
PreserveTube is a nice secondary archival site for YouTube videos. You can archive an entire channel (somewhat) quickly. You have to reach out to PreserveTube in order to archive videos longer then 1 hour, the site also "breaks" but if you refresh shit enough it'll eventually work. (Note: Do
NOT use PreserveTube as a primary archive for YouTube videos. Use mp4s.)
For archiving Xitter, you can use a Nitter site
(1) (2) then archive that Nitter link with GhostArchive/Archive.fo
This should be all you realistically need, remember to Archive Fucking Everything and don't be scared to ask questions/help in regards to archiving. It really is
that important.
