4 Billion requests per month involving 1 Petabyte of traffic doesn't seem like a "small SAAS", at least packet-wise. If its small revenue-wise, addressing that is a business concern as important as having your platform throttled for using the cheapo economy edition tier of whatever you've signed up for with Cloudflare. Did Cloudflare issue any formal communication with you warning about usage and how it violates contractual terms, or did they "ban" you out of nowhere?
