Blocking for URLs NOT on your site

@corE, hello, thanks for using the Autoban.
if I understood correctly, you're receiving requests like /wp_admin or /erwefdsfsd/sfsfsf . But if you have (for example) Articles pages (/articles) on your site it's ok for you receiving 404 error for requests like /articles/some_deleted_article.

Yes, I think it can be solved using some like Pattern Whitelist. So, if we put "/articles/" pattern to the list the /articles/some_deleted_article won't be banned. May be the best way is using pathauto patterns for generating list for this.

Thanks for the idea, I'll think about implementing it.

Note there is a module called Drupal Perimeter Defence → that does something very similar to what you want. Might be worth a look, and a comparison about what differs to make sure efforts are not duplicated and feature sets don't overlap too much.
