Fight SPAM! This plugin helps to ensure that your website authors and editors will not become victim to email harvesting bots by posting email addresses on the website. By using images rather than text, you will offer a higher level of security (arguably) against email harvesting robots. Features: 1. Use any font you wish! TTF or OTF supported. 2. Images are created in .png format to support transparency, or a specific background color 3. Change the font size; make the email images big or small! 4. Change the colors to whatever you want. 5. All changes can be done through the mambot administration panel How does it work? Its simple! Emails are automatically converted without any special work. Users don't even need to be aware that the emails will be converted! The script will cache the images automatically and use the cached images as available until you change the email or change your settings in the mambot.
