Thanks for your efforts! Actually, despite ArchiveTeam's statement of having captured 98.6% of public profiles, I wasn't able to find a single post (let alone a complete list of posts) of a single person I cared about on the Wayback Machine as a result of the last-minute scraping (there were a few that had been crawled earlier): neither any of my friends, nor people like Timothy Gowers, Terence Tao, John Baez, Linus Torvalds, etc. I just assumed it had somehow not been uploaded to the Wayback Machine yet, but if it's gone... oh well. Such is life. Thanks again anyway!
It's possible some content hasn't yet been ingested, though I'd thought it would be there by now. Just checked Archiveteam's pages, no clear info there.
