Yes, email addresses are obfuscated in PEPs.
For example, in PEPs 0 & 12, my address is encoded as "goodger at python.org" (the "@" is changed to " at " and further obfuscated from there). More tricks could be played, but that would only decrease the usefulness of addresses for legitimate purposes.
If some would find it useful, here is a snippet of code that obfuscates email addresses for HTML as done by Markdown (a text-to-html markup translator). It randomly encodes each charater as a hex or decimal HTML entity (roughly 10% raw, 45% hex, 45% dec). The email still appears normally in the browser, but is pretty obtuse when slicing and dicing the raw HTML. Would others find this useful in pep2html.py? ------------------- from random import random def _encode_email_address(self, addr): # Input: an email address, e.g. "foo@example.com" # # Output: the email address as a mailto link, with each character # of the address encoded as either a decimal or hex entity, in # the hopes of foiling most address harvesting spam bots.
