Try reaching out to the site owner via alternative channels (Twitter, Discord, Forums, ...) or email info@<the domain>. We cannot help you get in touch with them.
Include your Ray ID when contacting them. The Ray ID is should be located at the bottom of the block page. This will help the site owner identify why you were blocked.
