I haven't been following this in any particular detail - I have no
intent of using the system! - but this is certainly an issue they have
thought of and planned for; they currently describe the system as
"robust to cut-and-pase, delete-and-reinsert, and most type of
attacks..."

I suspect the papers linked at the bottom here -
http://wikitrust.soe.ucsc.edu/index.php/Main_Page - go into a bit more
detail about the algorithm.
