Here's my thought on 💭 Email Address Obfuscation · Cloudflare Web Application Firewall (WAF) docs
I recently started seeing email-decode.min.js show up on my blog posts, and I wondered what the heck ? I didn't put it there. Turns out that cloudflare put it there from pages to safely serve email addresses for me.
inspecting the page without js running we can see that the mailto email is swapped out for email protected. Neat feature.

Looking deeper into this article it looks like this feature comes from Scrape Shield and enabling Email Address Obfuscation.
