that doesn't seem very professional. is there another way?
not really. they scan webpages for email addresses. you could only allow email addresses to be displayed to logged in users. that would effectively block out spiders. other than that, you're stuck with funky tricks like those.
just thought of another way
try this: email @ domain . com
That might fool them
scrapers are pretty intelligent. I think this would be easy for the to figure out. They'd just make a rule that searches for @ signs and take x words before it, and x words after it, and create a few email addresses out of educated combinations. They don't care if 90% of the email addresses they generate are bogus.
basically, what you need to do is think of a scheme thats original, hard for a program to parse, but easy for a human. doing the same thing as everyone else does will not work, if everybody started adopting the same email obfuscation rule (i.e. everyone did "myemail_at_NOSPAM_ezabel_com") the scraper programs would just incorporate a rule to check for that format.
you really think that they go to those great lengths to parse out obfuscated emails?
