Twitter seems to have made an exception for archiving via the Internet Archive, so you can view tweets and profiles via https://web.archive.org/save https://web.archive.org/save if needed. They've not done the same for other archive sites like https://archive.ph https://archive.ph and https://ghostarchive.org https://ghostarchive.org though. Perhaps because those sites don't make their archiving HTTP requests with any header that identifies them differently from a common browser. Whereas the Internet Archive adds Via: Mozilla/5.0 (compatible; archive.org_bot; Wayback Machine Live Record; http://archive.org/details/archive.org_bot), Mozilla/5.0 (compatible; archive.org_bot; Wayback Machine Live Record; http://archive.org/details/archive.org_bot), 1.1 warcprox to each request, which allows for an easy detection server-side.
