I bought and installed the Q&A plugin.
It works allright and it's a nice idea, but spammers are making it impossible to manage in my website.
I have to invest too much time "deleting" 99% of the questions (garbage, numbers, links and xxx words).
For example, Intense debate makes a great filtering of the "normal" comments. Is there a way to stop spammers in Q&A?
I mean common filters like words, IP detection, urls in questions, etc.
Otherwise I will have to uninstall the plugin and forget the idea of questions for the site...
[I marked the option to review before publishing, but it's unusable at this spam rate... ]
Thanks for the help!
