The Abuse Module allows users to flag content as spam. It outputs an extra link at the bottom of teasers and full nodes.

The image above shows the link that is created at the bottom of nodes and comments that allows users to flag content for review by the moderators. The URLs that are linked-to have the structure http://example.com/abuse/report/comment/347. If you have a node with 15 comments, the Abuse Module will create 16 extra pages on the site, 15 abuse form pages for the comments and one for the node.
To fix this problem, the following rule should be added to your robots.txt file when using the Abuse Module:
Disallow: /abuse/
