It helps to know a couple tricks with archive.fo, add an * at the end of a link and it shows you all the archives of said link. Here are sone of the most noteworthy characters in this shitshow:
twitter.com

For facebook, you need links or write what is seen in screenshots you’ve found into the search bar and hopefully get lucky:
archive.fo allows you to create a copy of a webpage that will always be up even if the original link is down

DFE is the tough one. If its deleted and no one archived/screenshot it, it is gone. You could luck out and find a google cache of it tho.
