It seems that the flow has reduced somewhat in recent months: Alexa haven't been providing crawl data to the Internet Archive since January 2021. (You can see this by looking at the "Items" graph on the Alexa Crawls collection [0])
I was digging through their entries, this is the latest scrape that I could find. Haven't successfully unpacked anything yet, but it seems to be legit [1].
