Don't panic.

This here:

"worker": [
      0,{
        "total_burned": "13172141776315"
      }
    ],

means that it's a refund worker. The '0' above refers to the worker type, and as you can see from https://github.com/bitshares/bitshares-core/blob/master/libraries/chain/include/graphene/chain/worker_object.hpp#L95 , worker type 0 is a refund worker.

As you can also see at https://github.com/bitshares/bitshares-core/blob/master/libraries/chain/include/graphene/chain/worker_object.hpp#L62 , the refund_worker counts its refund volume in a member called 'total_burned', which is of course misleading.

Oh, and IMO it would be nice of you if you declined the payout from this post, because you're spreading FUD...
