My understanding is that ledgers are immutable but without a network of 
nodes supporting the ledger you can't append them so a user would not be 
able to continue to build up a reputation around a DID on a ledger than 
is no longer active. Maybe the user just creates a new DID on a 
different ledger and can present claims associated with the old and new 
DID and my concern is unfounded--which would be great. :)
