The "not" there feels like it's in an ambiguous spot, but at least gives a faint connotation of the author's intent, which reads as you'd like it to.

Even google doesn’t scrape the entire web every day.

I think it might be feasible to scrape a subset: a single account or a few accounts at most. But even then, you're still fighting problems ranging from wonky HTML generated through JavaScript towards sudden, unannounced changes to the DOM structure. It's not a managed API after all.
Scraping doesn't really help when publishing tweets, either.
