Yes. I've never bothered to obfuscate my email for exactly that reason, rather than for reasons of user convenience. If I were writing a program to crawl web pages for email addresses it would be extremely easy to include most of the common obfuscation patterns. If you really want to obfuscate then use some kind of image of the text, which is less easily machine readable.
