Today I came across the user profile of Foz at the wiki of the Chaos Communication Camp 2007. He’s done a really nice way of hiding his mail address from spam bots (I’ve done it now with my own address):
ruby -e 'puts "h!c!.!t!n!a!h!c!n!e!s!i!d!@!h!c!s!t!e!v!.!n!e!v!s".split("!").join.reverse'
Of course no normal or better say “non-geek” person will be able to contact you anymore but I think it’s a cool idea and of course you can rewrite it for your favorite programming language just like Python or Perl 
Btw. sorry to everyone that I’m not writing that much at the moment but I’ve really much to do. Don’t worry, I’m working on some nice stuff and as soon as possible I’ll inform you on what you can expect from me in the near future.
I don’t think it would take a spammer long to crack that code:-
javascript:str=”h!c!.!t!n!a!h!c!n!e!s!i!d!@!h!c!s!t!e!v!.!n!e!v!s”;str=str.split(“!”).reverse();alert(str.join(”))
Of course you’re right but I don’t think that a spammer would implement this into his address crawler because not enough people are using such a hiding technique. Also I never wrote that this is a secure way, just that it’s a nice way I’ve never seen before. For sure if a spammer really wants to break it, it’s about 5 minutes of work
