"Obscuring" addresses — by rewriting them in various ways — '''doesn't offer nearly the degree of protection''' against harvesting tools as the more effective methods discussed above. The alternatives of using JavaScript...and offering...contact forms...are both far more effective... On the other hand, obscuring addresses is often much simpler, as this approach typically does not require any programming.

Address "munging" typically consists of substituting words for symbols in the domain name parts of email addresses — "at" (or variations thereof) for the "at sign" and "dot" or "period" for the periods, and the like — as well as adding whitespace between each part of the address. Sometimes extraneous text is also added to the address, which a human reader would ostensibly know to remove.

I think it'd be safe to encourage people to change "foobar@freegeek.org" to "foobar at freegeek dot org" since no information is lost. A basic concept of a wiki is to enocuarage everyone to fix it where possible, not to create more work for the admins. RfS 19:12, 9 Dec 2005 (PST)

the risk of doing it that way

I agree, ease-of-use and utility are of very high importance. But how effective would that rule be? A study at Berkeley determined that it's not hard for "spambots" to crack codes like this. (I don't know if it's possible to determine how widespread this technique is.)

So I still think it's a bad idea for people to put more than the occasional email address in, even obscured like that. I think using a wiki page as an email list ought to be discouraged, since there are better tools out there.--Pete 19:38, 9 Dec 2005 (PST)

Here is a Berkeley spam harvest study.
