Adventures in Net Marketing: Email Cloaker

February 06, 2005

I came across this email cloaker. According to the developer, it combines all the different encoding techniques out there, and here's the result:

Basically, make it so that the only way to harvest the address is to fully render the page, JavaScript and all.

I've been using it on all of my sites (I used to use just a plain javascript encoder), and so far so good.

Listed below are links to weblogs that reference Email Cloaker:

I've started using a CSS trick I learned if I want to use my email address in a page (very very rare - and it's usually a throw away addy).

write your email address out backwards:
ex: moc.elpmaxe@uoy

Wrap it in a specific div
Ex: moc.elpmaxe@uoy

And in the CSS file, write:
.email {unicode-bidi: bidi-override; direction: rtl;}

This works with IE 5.5+, FF, NN, Opera, etc. (I've had reports of it not working on older versions of IE on Mac).

I owe that trick to the folks over at css.weblogsinc.com

And of course, my never fail spamfree method - simply use a contact form with my email addy embedded in the script :)

Another good one! Thanks, Teli.

I should probably mention that the above div example should be:
div class="email"moc.elpmaxe@uoy/div

Forgot about that whole HTML autoformatting thingy
