Scraping services work by going through thousands of intermediate proxies run on unsuspecting people's compromised computers. Each scraping request will be a unique IP with a normal looking header.

They may be able to look at the number of unique requests per account but given the ridiculous amount of spam/bots that exist clearly creating new accounts isn't an impediment.

The far more likely scenario is that they were throttled by AWS/GCP for not paying bills and are behind on their migration project.
