This class can generate HTML tags to display text using CSS in such way that it prevents harvesting bots to determine what is written.
CSSProtector is based on an idea from Stu Nicholls about using CSS Font as a protection method against spam bots.
CSSProtector renames all the CSS classes used to protect the string everytime it is called, so the same string looks the same to the user but different to the bot everytime.
For Internet Explorer and Opera, CSSProtector only works on pages that use the STRICT DTD. For Mozilla it works well with STRICT and LOOSE DTD. Older browsers that do not support CSS will show nothing or a whole mess.

 May 2005 Number 5 Prize: One subscription to the PHP Magazine |
One of the reasons why people get so much spam is because they left their e-mail addresses exposed in public Web site pages. Over time many solutions have been implemented to make it difficult for robots that crawl pages in the search for e-mail addresses of spam victims. Most solutions consist in ways that make it easy for human users to read the e-mail addresses, but very hard for robots to extract that information from pages. This class implements an uncommonly astute solution that uses combinations of presentation styles with CSS to present the e-mail address in pages that is hard for most e-mail harvesting robots to extract the addresses.
