Seems like you might have been blocked for abuse. If you can join the Discord server (https://workers.community) I can have it looked into on Monday when the team is around.
Hello, you should have received an email from Cloudflare (or Github, depending on which account was suspended.)
If you have received an email from Cloudflare regarding suspension:
Reply to the email stating why you think you did not violate the TOS mentioned in the email (as the reasoning for the suspension should be in the email)!
If you received an email from GitHub regarding an account suspension:
Please post this topic from within the GitHub Community, as CF has nothing to do in this case!
This issue is about not being able to create Cloudflare Pages projects. I still have full access to rest of the products on Cloudflare, and my Github account is fine.
