I'm looking at Craig's List's email obfuscation, and I can't figure out what method they use. I thought it was hex with a few added characters in there, but that wasn't right. If you look at the source of a Craig's List ad the email looks a lot like this: & #112; & #101; (the spaces don't exist, and these are a lot more of these, one for each character) What is this called? It's not hex because it's more than two characters, and it has a pound sign an a semi colon. Thanks!!
