@BrentWilson:

This mod is focused on improving SEO on a per thread basis, allowing admins to require users to provide a post of significant length and/or make a demonstrated effort to contribute to the community (i.e. minimum post count) before giving them the privilege of displaying their signature (and/or having links within their signature free from rel=nofollow attributes).

This is particularly important for vBSEO-enabled forums who can generally expect to have a higher Google PageRank on their thread pages. Reducing unnecessary use of signatures with outbound links can conserve PageRank.
