I think that the evidence you mention is nothing more than what is documented on how pagerank works for incoming links, which is described in the Wikipedia link I included above.
It is not evidence that pagerank leak does not exist.
Again, this is a simple mod that was requested by some of our members because
NuWiki was doing this for wiki articles that were not created.
The name of the game is choice. You can download and install this mod, or you can choose not to install it.
Even if you choose not to install it, please click the 'Mark as Installed' above. It will increase my
vBulletin.org Pagerank..
