Logic is used to identify spam comment submissions. No user interaction is required. The spam blocking mechanisms work transparently behind the scenes. Most visitors will require longer than a few seconds to read a post and add a meaningful comment so any comments submitted within a short time threshold are identified as spam. Comments containing a large number of links are flagged as spam. The plugin uses an encrypted code and a honeypot to filter robotic submissions. All field names added by the plugin are randomized to prevent detection based on a source code signatures.
Configuration options include:
- Add spam to WordPress queue or block completely
- Send diagnostic information to site administrator
- Automatically compatible with the Micro Contact Form plugin to block spam messages.
Blocking options include:
- Honeypot Trap
- Randomized Internal Field Names
- Timestamps (minimum and maximum entry time)
- Aggressively check for excessive URLs
- Automatically block repeated spam from IP
- Automatically block repeated spam based on content
- Require User Agent string
- Require Referer
- Block Trackbacks
- Block Pingbacks

Why did I still receive a spammy comment?
The plugin uses a number of methods to block spam comments without requiring additional human interaction (captchas). While these detection methods significantly reduce automated spam, they may not block all low quality, human entered comments. Use the diagnostic e-mails to establish the appropriate settings and thresholds to block the most spam. The plugin only blocks spam comments submitted through the default WordPress comment form.
Does it work with other comment plugins?
No. The plugin only blocks spam comments submitted through the default WordPress comment form.
Timestamp blocking is not working.
