CloudFlare email protection

[bkil]

Is it intentional that it obscures phrases that look like email addresses (visible when JavaScript is disabled)? Presumably also happening with Fediverse accounts, root prompts, etc.

This is unintended and I wasn't aware of this happening. It doesn't seem like a totally bad thing to have enabled though. I could really go either way on this one 🤔

This appears to be "Email Address Obfuscation" from Cloudflare as you surmised.

For reference, when JavaScript is disabled the [email protected] text is linked to https://archive.matrix.org/cdn-cgi/l/email-protection which is served from Cloudflare with the following content. With JavaScript enabled, the content appears like normal.
