Does that even work on 4chan? On /b/ threads can vanish in less than an hour. There used to be specialized sites such as 4chanarchive to fill the gap, but last I checked most are dead.

Afaik there are various ones still existing, but dunno how ephemeral they are (eg archive.moe supports /b/), and how much they miss

And then you just webarchive archive the archive sites instead of 4chan directly :-)

Well, this particular thread still exists; somewhere in the Tweets there there was a link posted to an archived version.
