Is it worth obfuscating email addresses on the web

Question

There are various ways to obfuscate email addresses on the web, but most of them don't work when you need to have a mailto: href.

I generally use name[AT]domain.com, because I think it's fairly obvious to the user what they have to do to get a real email address, but I wonder if there's any benefit to this (as it's easy to automate by a spammer). I'm aware of the services which hide the email address behind a captcha, but to me this is too much work for the user.

So, two questions:

1. Is there any way that (a) retains the use of mailto: links, (b) will stop spammers and (c) isn't too complicated for non-power users to work out?

2. Is it worth it? Do we just accept that spammers will find a way round it and just use Gmail?

Edit: I should mention that, in this specific case, I'm talking about the contact email address for the companies whose websites I'm making, on their websites.

Answer 1

Are the email adresses yours? (your company?) or are those user email adresses.

For user adresses I would use some obfuscation or a login wall. For personal email adresses I would not use any walls but I'd make sure everyone has some sort of spam filter.
