Selkirk;

I very much like the idea that the Sandbox may be linked to TrustRank as I can believe it is possible that the addition of TrustRank to the algo created the Sandbox effect.

However, I think a few of the details may require additional consideration.

B. The everflux crawl for assigning PageRank detects a spammy linking pattern. If the SpamRank is higher than the TrustRank, the whole site is marked as spam. PR shows as n/a. Why waste time calculating PR for spam sites?

Sandboxed sites can and often do show PR.

Low quality stay "in the sandbox" due to their combined low TrustRank and high SpamRank.

If I follow the above correctly, unless TrustRank naturally increases over time for boxed sites, they would not be able to come out of the box without removing the causative violation.

In my mind, it is the "self-lifting penalty" aspect of the box which distinguishes it from other forms of penalization.

I think you are headed in the right direction.
