I am still on Vercel (yes I know, trying to migrate off...) and it gives you automated alerts when there are anomalous traffic spikes. Funnily enough, I have had about 10 scrapers from various places scraping the site in the last week.
I hope you're adding some fictitious entries (https://en.wikipedia.org/wiki/Fictitious_entry) to track where those scrapes might be going.
Most of that is tends to be over pricing or Next.js, when there's probably loads of quietly happy people using it, but... Those people are quiet, so it is hard to tell.
