Spam Deterrents

No other publishing platform gives you as many tools to prevent comment and trackback spam as ExpressionEngine.

• Blacklist
  The ExpressionEngine Blacklist/Whitelist Module is an integral part of EE's spam prevention capability. This Module allows you to specify URLs, IP addresses, and user agents that you want to deny (blacklist) or specifically allow (whitelist) from your site. The blacklist is checks all content that is submitted to your site. ExpressionEngine will compare the submitted content against your blacklist/whitelist and then behave accordingly.
• Captcha
  A CAPTCHA is a computer-generated test that humans can pass but computer programs cannot. Since a great deal of spam is generated by automated scripts or "bots", a CAPTCHA can be effective at preventing their use. When the CAPTCHA is enabled, an image containing a random word appears next to the comment and member registration forms. In order to submit the form, the word must be typed into a form field.
• Comment Time Interval
  This setting defines the amount of time that must lapse between comment postings. A malicious user will have to wait until the time has lapsed before being able to post again.
• Rank Denial
  The primary goal of spammers is to have their sites ranked highly in Search Engines in order to generating more traffic for themselves. They achieve this by posting comments at your site which contain links to their own site. The more links to their site scattered in weblogs across the internet, the higher Search Engines will rank them. The Rank Denial feature denies a spammer this "ranking" benefit by altering all links submitted by users so that they point to an intermediary "redirect page" at your site first, before being sent to the target destination.
• Secure Form Mode
  Secure Form Mode prevents automated scripts (the most common way spam is generated) from repeatedly submitting comments or other form data. A submission is only allowed when a user manually loads a page and submits the form from your site. And once the form data is received, the user has to manually reload the page before they can submit again.
• Duplicate Data Denial
  The "Deny Duplicate Data" feature prevents a comment from being accepted if an identical one already exists in your database. A malicious person can't submit the same information more than once.
• Trackback Pings Per Hour
  This setting defines the number of Trackback pings you will accept in one hour. Trackback spamming can be a concern as well. By limiting your site to receiving a finite number of trackbacks per hour, this limits the number of malicious trackbacks you can receive.
• Trackback URL Randomizer
  The Trackback URL to a given entry is randomized with every page load. And when your site accepts a trackback, that particular URL is no longer accepted. This feature deters automated trackback spam since your trackback page must be loaded before a trackback can be sent.
• Site Membership
  Although this isn't technically a security feature, requiring your users to be members of your site provides additional safety against spamming since you have better control over the people posting on your site.

Utilities

ExpressionEngine’s powerful utilities help you manage your site.

• SQL Manager
  A full complement of SQL utilities, including database optimization, database backup, manually submitted queries, table info, process info, and more.
