The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Avoiding spammer "harvesting" of your site's email addresses

Zone: Hypertext Markup Language (HTML)

Tags: email, harvest

Having set up a website some four years ago, I'm now on the list of almost every spammer on the net. Looking at my server logs I see almost every day an unidentified bot come through the site (i.e. not one I recognise as being from a search engine) as they harvest the information they find in the "mailto:" tags.

Spam in my inbox is an annoyance, but it costs me nothing but time (I have a flat rate internet account). Now, however, I want to include in our site a form which allows the visitor to send a message instantly to my pager, which can be done via an email address.

What I *don't* want is for that address to be harvested and to pay 20 cents a message for my mobile screen to be filled with ads urging me to buy CDs crammed with other harvested address, hot stock tips, and exhortations to increase the length of parts of my anatomy.

I remember reading once that it is *is* possible to sabotage address-harvesting bots (they still get the information but it's unusable and bounces back to the spammer unless they manually edit it?) but still have the form work. Any idea how?
