coding an email address to avoid spam harvesters?

Is this possible?

Is there any way to include your email contact on a webpage, besides listing it to look like ... mail at mysite dot com ?

do i just have crappy spam filters? most all professional companies have their emails listed directly with the @ and . how do they avoid getting scraped by spam harvesters?

even using forms or mailto: feature you still have to code the email address. can anyone help me here? i hate spam to death. heavan help any spammer that would ever cross me in a dark alley.

you could always make an your email address an image. people won't be able to click on it to mail you but it should work to avoid spam harvesters.

Listing your email address in the form "name at domain dot com" isn't really safe nowadays either, as most email harvesting spiders look for several patterns, including that one.

Like DomainsInc said, creating an image of the email is your best bet. As far as mailto links go, I personally hate them and never use them. In the case of a mailto link, there's no way to get around it, because like you said, you have to include the email address in the html markup.

Use a 'captcha' and obfuscate the target email address string, character by character with a simple logical operator so it's not readily visible in the source. This for the paranoid only

You can do it with javascript:

Code:
<script type="text/javascript">
var y = "contact"
var z = "example.com"
document.write("<a href=\"mailto:" + y + "@" + z + "\">" + y + "@" + z + "<\/a>")
</script>
If you want to make it trickier, break up the domain into more than one variable.

Great dicussion on an ever present challenge to keep email addresses protected. I thought I would add two more suggestions: E Cloaker 2.0 and MailTo Protector. Both are email link generators and encoders that significantly reduce the possibility of spam bots harvesting email addresses from a web page.

I had been using a simple .gif image and informing people to typein the unclickable image address to send email by using the ALT Tag message which appears upon mouseover. It's free with insignificant amount of work involved.

I use this method. Sometimes i put an image too

And sometimes i put some hidden HTML characters between real e-mail address

For example the real e-mail address is "admin@example.com" :
Code:
ad<span style="color:#000;display:none;" id="xawda">sdxasjdkw</span>min<span style="color:#F00;display:none;" id="a019s">sdxasjdkw</span>@exa<span style="color:#FC0;display:none;" id="ab1n9">mination</span>mple.com
And the visitor still see the above as "admin@example.com"

You could just use a contact form. Or you could create a clever javascript challenge such as "slide the slider to the end of the bar to reveal the email address".

Not everyone is a fan of it but you could create a very small flash file link on the page. Spambots don't know how to deal with flash files.

I was going to suggest this. It can easily be done in most image programs including MS Paint.

this is my point about the flash (.swf) file. People would still be able to click it and it would also be visible just like an image. And spambots wouldn't be able to deal with it. You could even have the email address get retrieved dynamically by the swf file from either an xml or database field so that the address isn't even embedded in the swf.

Does email harvester see source code or visible page?
If it sees source code, you can simply encrypt html code, no?

I really would like to know this, so, let me repost.
Could someone answer this?
