Simple way for hiding your email address

They say that SPAM bots are really good these days and can figure out your e-mail out of many “traps”.

I wonder, if they can catch it out of something like this:

<a
    href="mailto:me.nononono@domain.nononono.com"
    onmousedown="this.href=this.href.replace('.nononono','')"
    onkeydown="this.onmousedown()">
contact me</a>

I prefer to think, they don’t and that they’ll crush their ugly spammy teeth on this! :]
