If you are interested in knowing where the files are coming from turn
on audit logs on the file servers.  That will erase all doubts.

But lets make something absolutely clear.  If you have volumes that
permit system:anyuser to write to it, there does not have to be any
spam involved.  Any machine with any AFS client anywhere in the world 
can write to the volume.  There is no need to send spam.
