When writing via freebase.com, the attribution should always show the  
writing user.  I do not believe there is any mechanism available  
standard MQL to change this,

Some of our large internal data loads, such as the wikipedia update,  
use a specialized "attribution" node that is cotyped with /type/ 
attribution and /dataworld/provenance.  The properties of these type  
contain information about the dataload, including the information  
source and software tool used for loading.

However, the attribution mechanism is not generally available for  
annotating links in general, nor is it accessible to users via  
freebase.com.

Currently, we do not support any mechanisms for adding properties to  
links -- except for the exception of sort index.

In any case, attribution is probably not the correct way of doing  
this, as re-attributing to a "protected user" would obscure the  
original provenance of the link.
