If you look at the page sources around here you might notice that
there are no bare e-mail addresses around. This is because I obfuscate
them into a series of HTML entities. So far this has been pretty
effective at hiding from address-scraping, web-crawling spam
bots. They don't seem to try very hard at decoding HTML entities.
When I added the comment system, I needed to obfuscate addresses
automatically. I quickly realized that this is yet another perl
one-liner (and implemented as one line in the comment system). It can
be used on the command line to obfuscate a file/pipe containing a list
All of the spaces are really only there for us humans,
