Anyone Using Email Riddler

[sassafras9]

Hi,

I came across this free script at Dynamic Drive forum called Email Riddler.
http://www.dynamicdrive.com/emailriddler/

This is their description.
"Email Riddler is an online tool that encrypts and transform your email address into a series of numbers when displaying it, making it virtually impossible for spam harvesters to crawl and add your email to their list."

Is anyone using this? Does it really help prevent harvesters from getting your email? If it does, is it just a matter of time before harvesters are improved?

Any posts appreciated.

Thanks
