I don't support or use VBseo (there are reasons), but Google made this announcement within the past month so I find it unlikely they have implemented anything like this.

If VBseo currently assigns nofollow to user signatures and other user contributed links, then yes, this would be an improvement. If VBseo currently does nothing to such links, then yes this would be an improvement. The only way this won't be an improvement really is if VBseo currently does this exact thing.

In fact, VBseo may be hurting you. Doing some Googling it looks like VBseo may be using rel=nofollow to block even some internal site navigation, such as to printthread.php, this will result in that link weight being lost now, not retained as it was until recently. The proper solution is to use the new canonical link element to define the canonical URL for the same content source (ie, showthread.php for all printthread.php locations). Ever since the announcement webmasters have been scrambling to remove nofollow from any and all internal links that had it, it can only hurt you to use it in that fashion now.
