  Anomaly DERP-1728 broadcasts high levels of transactions,
  primarily from the on-chain account known as
  "crystalliu."
  
  Examples of anomalous transactions are as follows ...
  
  === Content Edits ===
  
  A majority of DERP-1728's resources credits are consumed
  by edits.  What follows is a sample of the content with
  the highest edit counts, author is crystalliu:
  
  | Permlink           | Edits |
  |--------------------|-------|
  | 0ubftv89alx        |    95 |
  | 1f6d0u549fv        |    94 |
  | 4y2fi265tfk        |   124 |
  | 5opauprbpla        |    89 |
  | 5tydnh-crystal-liu |    94 |
  | 7eweij3a3ix        |   236 |
  | 9qos3tj6gkf        |   101 |
  | bp9vtmtwri2        |   144 |
  | dgz2lczg9yp        |   101 |
  | f3yhx6ikfnx        |    96 |
  | goq36u4juyf        |   119 |
  | h4xhc053p1p        |    88 |

  | oylkvhxamvx        |   171 |
  | q00s9g             |   118 |
  | q04vu7             |   186 |
  | q06heo             |    89 |
  | vpvvir6wf5o        |   102 |
  | wmb62opntky        |    99 |
  | y4y7wbbov0w        |    92 |

  What is particularly anomalous about the above table is
  that nothing about the content changes in each edit.  The
  same content title, body, metadata is just repeated each
  time.
