I've installed Q2A-Akismet-Plugin-v2b3, on q2a 1.6.2.
I've done some tests to better understand its behaviour.
I've used some typical spam comments intercepted by akismets ( see here : http://allyouneedislists.com/technology/10-awesome-spam-comments-intercepted-by-akismet )
Akismet detects these comments as spam when I use them inside comments or inside answers.
If I use them inside questions they are not detected as spam.
I do not want to discuss about Akismet's algorithms, but I've not been able to see *1* question been intercepted and moderated by the plugin.
Any suggestions ?
Do you have an example of a "spammy question" ?
