To make scraping your material more challenging, use Noscrape to obfuscate text using nodes.
The secret is to use any true-type font as noscrape creates a new version from it with jumbled Unicode and no way to compute the characters back. Obfuscated strings and integers can only be read by utilizing the created obfuscation font.
