HTML - CSS - JS - Mail obfuscation on webpages

Question

Considering that e-mails (for instance, Contact e-mails) on webpages can be "captured" with web scrapers (and then having to suffer spam as a consequence), what techniques would you use to address this problem? Preferably without using Google's CAPTCHAs.

Even more, a solution without involving JS would be more than excellent.

What is your personal approach about this problem?
