Today I received an email that my web property is in violation of Section 2.8 of Cloudflare’s Terms of Service and they have temporarily stopped serving some of the traffic at issue.
Best thing to do is open a ticket with Cloudflare Support from the dashboard. I’m assuming you have a ton of videos and basically no HTML content which per 2.8 Use of the Services for serving video or a disproportionate percentage of pictures, audio files, or other non-HTML content is prohibited, unless purchased separately as part of a Paid Service or expressly allowed under our Supplemental Terms for a specific Service.
Whether or not you are caching the video is not the issue, you are delivering video through the CF network in violation of the TOS. You need to deliver video through a separate hostname which is , or have a commercial agreement to deliver video.
