Does "assembling" an email address on a page with javascript prevent spam?

Question

JavaScript

Starting with the most primitive options:

document.write('<a href=mailto:qwe' + '%40' + 'rty.com>mail</a>');

and ending with a variety of "tricky" decryption functions with character lookup tables or n-character shift coding.

Answer 1

Answer 2

It will definitely save you from some bots, although there are some that can even recognize a picture with a box in auto mode.
