Noticed something which might be simple to adjust:
Say you have WP installed in the web root and the webhost offers a cgi-bin with for instance awstats and such, those files would be scanned as well.
Even though that can be useful, those file are outside the wordpress scope.
So I'm thinking that it would be really useful to have an admin setting where one could add directories to skip.
What do you think ?
If you like, I'd be happy to code it if needs be.
Hope this helps.
