Cloudflare, a popular web security company, occasionally blocks user access to websites it protects if certain criteria are met.

This is part of its service to safeguard sites from online attacks.

Actions that may lead to such blocks include submitting specific content or attempting suspicious activities through the website.

Users faced with this block can try resolving the issue by emailing the site's owner and including relevant details such as their actions leading up to the block and the Cloudflare Ray ID, which is found at the bottom of the page displaying the block message.
