Mixed numeric entity generator to defeat deterministic scraping algorithms
CSS unicode-bidi RTL direction reversal (backward source code, forward visual rendering)
JavaScript dynamic DOM assembly for clickable mailto: links invisible in raw HTML source
Hex byte escape sequences (\x68\x65...) for JavaScript, Python, and C++ code
Live human browser visual sandbox verifying natural visitor appearance
100% private in browser memory processing with zero server uploads
Frequently Asked Questions
Will human visitors still be able to read and click my email address?
Yes! Web browsers automatically decode HTML decimal entities and render CSS RTL reversed elements into regular readable text for human visitors. JavaScript assembly can also automatically create clickable mailto: links.
Why do spam bots fail to scrape obfuscated strings?
Most automated scrapers and scrapers use simple regular expressions (like searching for [a-zA-Z0-9]+@[a-zA-Z0-9]+) on raw HTML source code. When your email is written as HTML entities or injected via JavaScript, the raw pattern does not exist in the source.
Which obfuscation method provides the highest protection?
JavaScript Dynamic DOM Assembly provides the strongest defense against simple and intermediate bots because the email address does not exist anywhere in the initial HTML file until client-side execution.
Are my private contact emails or secrets transmitted to your servers?
No. All encoding and string manipulation runs 100% client-side in your local browser memory. Zero data is ever logged or transmitted over any network.
