Super Simple Anti Spam for WordPress is anti spam plugin (for comments and trackbacks), while not having to moderate and / or edit a single setting.
It is designed to attempt to stop all spam, without any annoying stuff for the users (or you). We can never gurantee it will stop all spam.
Trackbacks is a bit special, its not a comment and is not something that can be moderated the way this plugin works. Currently trackbakcs can be posted without the plugin does anything. This is something we are looking into. Trackbacks should now be scanned and stopped if spam. Not 100% effective, but close.
The only change you as admin and / or user will see is the comment author field is moved down to last place (normally its first thing you fill out). Sometimes you do not see this change either ( depends on other plugins ). If you want to test if the plugin is installed. Right click anywhere and select " Show Srouce " - Search for "ssas-author" or "ssas". If you find one of them and its a input field. Then it is installed. To check if its working, try to post a comment. Note: you cannot simulate a bot comment by just posting a comment. You will need to edit a bit to do so.
