Well, there is a problem with this idea, admittedly. All the missing posts are from one user, @AkaSci@fosstodon.org
At the same time, however, it doesn't look like he suddenly became a Musk fan, so...
There's also no archive of these apart from Google's previews.
This is the only Elon-critical post from this user that comes up on Google and hasn't been deleted:

EDIT: I contacted AkaSci, and he informed me that he more than likely did delete those posts, as "I tend to delete old posts that are political or news related." So it seems there's no evidence his abuses have leaked onto FOSStodon yet.
Yeah, the Bell Riots are considered to be one of the biggest turning points for humanity in Star Trek.
But I think we have what it takes to reach that point and just keep digging.
