This method of "cloaking" is very popular, so most email spiders can easily harvest your email address create lists for SPAM:)

It's better to encode it with Email Cloaker.

Not everyone/everything (person/machine) is savvy enough to translate something like "user at example dot net" into a valid e-mail address. That method of obfuscation may be useful and sufficient in certain contexts, but it's too "geeky" in situations where it's important for certain people to make convenient contact. Really, it would only take a couple minutes to find someone who doesn't understand it.

I don't claim to be an expert on which people-friendly, spam-unfriendly contact methods to use but anyone who disagrees with my observation about that particular type of address obfuscation is living in a vacuum, isolated from the reality of how naive and ignorant many Internet users still are about what others take for granted.
