Cloudflare is a security service provider that protects websites from online attacks by acting as a barrier between the site and its visitors.

When users encounter a 'blocked' message on a Cloudflare-protected website, it usually means that certain actions or inputs triggered the security system's response.

This can happen due to several reasons, including submitting specific words or phrases that are flagged by the security settings or attempting to execute malicious SQL commands.

In some cases, malformed data submitted through forms or contact pages could also activate this protective measure.

To resolve such issues, users are advised to contact the site owner directly, providing details about their actions leading up to the block and referencing the Cloudflare Ray ID found at the bottom of the error page.

The website owner can then review and potentially lift the ban if it was incorrectly triggered.
