Summed up very well Justin.
And yes, Apple Mail is the best way to defend against spam (junk mail). 
 It has an awesome spam filter system.

As soon as a new technique for hiding email address' becomes widely 
publicised, then *everyone* knows about it.  Yes, that includes the 
makers of spambots.

All they'd need to do is crawl linked stylesheets looking for 
content: ...;, and then realise that \40 is an @ symbol, and hey 
presto, they've found another set of email address'.

Seriously, there is no way to avoid spam if you plan on making your 
email address public on a  webpage -- plain and simple.  if you have a 
way to encode it, they'll find a way to decode it.  To live in the 
myth that we, the humble web developers, are smarter than hundreds or 
thousands of super-geeks writing spambots to fuel their BILLION DOLLAR 
industry is ludicrous.

Yes, they could decode and read javascripts, yes they could read 
linked style sheets, yes they can attempt to detect text inside images 
and yes they can beat whatever else you can come up with.

The ONLY fail-safe method of hiding your address from spambots is to 
NOT PUBLISH IT, which means you need a contact form which only lists 
names or nicknames of staff members... matching that name to an email 
address is done server-side with PHP (or Perl/ASP/CFM/et al).

Even then, it's not much of a stretch to imagine a spambot parsing the 
form and guessing email address' based on the names in the form, 
combined with the domain name.

As said earlier in the thread, spam is best defended with filtering at 
the receiving end -- I get 50-100 spam messages a day (in addition to 
the ones caught by my host server-side), of which Apple Mail catches 
about 98%.

Also, on Firebird you can't copy and paste the email address which is a bit
annoying.  Also, it would be a bit annoying to deploy on site where the email
address links are generated dynamically, you'd need to generate a bit of CSS as
well as the link.

All in all, I wouldn't use that method.

I use the following javascript. It works well for me.
script language=JavaScript!--
var name = insert username;
var domain = insert domain name;
document.write('a href=\mailto:' + name + '@' + domain + '\');
document.write(name + '@' + domain + '/a');
// --/script 
just place it in your code where the usual a href tag would go.
If you want to add a class to it, it goes here -- domain + '\ class= ');

How's about:

At least you're covered whether  or not JavaScript is enabled.

Nice concept -- but -- all it takes is for a spammer to start harvesting 
based on the \40 string and stream substitute it for the @ into 
their DB.

Given the incompatibility with IE, the fact that Firefox cannot copy + 
paste it, and the large amounts of CSS for more and more email addresses 
on a site, it suddenly becomes a not-so-good idea anymore.

To make matters worse, if someone were to publish their business' email 
addresses like this in a single CSS file - well... can you imagine every 
email address available for a spammer to download? That would be like 
hiding the keys to your house under a fake rock. That's pink. (Well, 
maybe harvestors don't parse CSS, yet...).

Re: [WSG] Hiding email address from spambots with CSS

2004-07-06 Thread Mark Stanton
HI All

My thoughts on this issue are here:
http://www.mail-archive.com/[EMAIL PROTECTED]/msg05509.html

If doesn't really matter what obfuscation method you use:

- If its visible to users spam harvestors can get it if they really want to.
- The more you hide it (via js, css or what ever else) the more you
lose on accessibility.

Spam has to be stopped on delivery - hiding email addresses is a
bandaid solution and a poor one at that.

Cheers

Mark

Of course. The point is just to make it more difficult. A car alarm 
doesn't stop car theft, but with all else equal, the thief will choose 
one without an alarm.

That's fine  true but by making it difficult for spam bots you also
make it difficult for your users.
