Have you ever had the need of putting your e-mail address up on public domain, but you’re afraid of spam bots harvesting your email address?

This is a cool CSS trick that you can use to prevent spam bots from harvesting your e-mail address.


Looks pretty normal right? But view the source and this is what you get.

<span style="unicode-bidi:bidi-override; direction: rtl;">gro.natluap@luap</span>

Spam bots would only be able to harvest the gro.natluap@luap which obviously isn’t a valid e-mail address.
