We may be inadvertently increasing internet search ranking for spammers via reaped nodes. Nodes that have been reaped for spam often include links to other sites. Although the links no longer show in the original discussion context, the text of the node, including all links, is one click away ('You may view the original node and the consideration vote tally'). Search bots will crawl this page, follow the link, and index the spammer's site. Since our site is well-ranked on the internet, this will boost the ranking of the spammer's.
We should neuter these links by either adding the nofollow option or converting them to plain text.
