The scrapers most likely don't use the VPN providers AFAIK. But the datacenter clusters, so there are dozens of cloud providers where you can rent your own virtual server and those datacenters are also often used by VPSes.
Its actually often coming from separate IP address. Which makes it actually even harder, its not just 1 or 2 IP addresses. Meaning both good and bad traffic has 100.000's of unique IP addresses. At that point I block the whole ASN: https://www.cloudflare.com/learning/network-layer/what-is-an-autonomous-system/

Meaning I basically block the whole datacenter and mark them as bad actors. Cloud server providers F*K up the internet, since before you can easily block one, two or ten IPs and be done. Today, those bad actors and scrapers or DDos attackers can use millions of unique IP addresses, because it can rely on the whole cloud provider IP ranges (ipv6 is even more insane ofc).
