Agreed. It's better to use something like reCAPTCHA Mailhide (http://www.google.com/recaptcha/mailhide/) to protect your email address.

True, I'm not sure how effective such obfuscation is anymore, but for the thousands (millions?) of pages out there that will never be updated, at least this fix will save a few seconds per paste. At the very least it was a fun and satisfying hack.

I don't agree with that necessarily. As someone who used to scrape the web daily, I can tell you that most software doesn't have that level of sophistication...

i read a few days ago about a large-scale-y investigation about "obfuscated" and real email-addresses. it seems that it is better to just write me@example.com instead of me(at)example.com as you can find the second pattern through google queries while you won't find the first one. i.e. google is smart enough to not let scrapers use its index for easy listings.
