There is an explanation of what is going on; it might be incomplete, but your account has in some way been flagged for fraud or spam. Maybe someone else is abusing your account, or maybe you have a miss configuration causing this to trigger, but I'd reach out to a service rep.

I've experienced a near opposite situation: there was a news story about cloudflare providing ddos protection for a number of websites including the site for "The Proud Boys" (if you haven't heard of them, they're an all male far right american political group fairly well known for their physical fights with various other groups). My client, who was often vocal about politics on their public CEO twitter account, made a statement that if Cloudflare did not end their contract with the proud boys and a couple other unsavory groups then he would find an alternative and move all his current and future projects away from them. So it quickly fell to me to move all his legacy properties off Cloudflare and close out their old account... and while they may have lost him as a future customer, after the pain of trying to find similar levels of service for a similar price I am now recommending Cloudflare to most of my clients over their competitors for ease of use and pricing.
