I've set up several spamtrap addresses to study this. Eventually I'll
write a short article about my findings, but in the meantime I'll
summarize here. I have three email addresses all on the same page. One
is naked (i.e. just foo@example.com), one is entity encoded (i.e.
foo etc.) and one is added to the page by Javascript.
The number of spams each has gotten to date is as follows:
naked - 715
entities - 2
javascript - 1
In short, the entities look pretty effective to me. They're nice because
they don't disturb one's visitors at all and you don't have to mess
around with any Javascript.
But another way of looking at it is to say that Javascript protection is
twice as effective as entity protection. =) (Thanks to Huff's "How to
Lie with Statistics")
