EMAILProtect Version: 1.4 plugin by Jacob Hallsten uses regular expression to locate, split and replace the e-mail string with a JavaScript function – which put the parts back together and print a clickable e-mailaddress.
Most crawlers thees days are “non-javascript crawlers” (to speed up the crawling process) which means that almost no crawlers se the e-mail address – even though it look just the same for the regular user/client.
