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

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%. --- Justin French http://indent.com.au * The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list getting help * * The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list getting help *

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

Neerav wrote: I havent tried this, but it sounds interesting http://www.phoenity.com/newtedge/hide_email_spambots/ 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...). -- /** * Adam Carmichael * [EMAIL PROTECTED] /( _,-,_ )\ _| |_ /,|| * #1 Computer Services \`/ \'/ _| |_|| * BSD/UNIX Cisco Network Engineer\ /,\ /,\ /| |_||_ **/ * The discussion list for http://webstandardsgroup.org/ See http://webstandardsgroup.org/mail/guidelines.cfm for some hints on posting to the list getting help *
Re: [WSG] Hiding email address from spambots with CSS
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.
