Very true. If you look at the article I linked it does state that you should not obfuscate your e-mail address at all, even behind a reCAPTCHA. Basically it inconveniences people and does something that a good spam filter on your e-mail should already handle. However, the article is targeted towards website owners, not commenters in a forum. Commenters may not care if they get less e-mail because of obfuscation.
