It is not mentioned that empty user names after trimming should be filtered.

Excactly how are the entries to be sorted? I thought it was order id -> reverse alphabetical/ascii

I can't get past random - the entries there do not look sorted on order id. From my log :

to deeply equal [ [ '3v', 0 ],
  [ 'Hz', 74 ],
  [ 'q8$a4', 74 ],
  [ '^', 3 ],
  [ 'y', 3 ],
  [ ')d', 3 ],
  [ '9', 3 ],
  [ '3s', 65 ],
  [ '^M&^L', 65 ],
  [ 'W!', 65 ],
  [ 'x', 65 ],
  [ '4q(', 48 ],
  [ 'I', 48 ],
  [ 'KQ', 85 ],
  [ '$', 85 ],
  [ '4BC+', 85 ],
  [ '6W)M', 9 ],
  [ '@T', 8 ],
  [ 'K+0)', 8 ],
  [ '@W9', 57 ],
  [ '(J!@OT7XL', 57 ],
  [ 'w$GWu6', 7 ],
  [ '5Z', 7 ],
  [ 'Z!s', 7 ],
  [ 'dbJ', 85 ],
  [ '!Z', 14 ],

Name/id pairs should be tuples in the languages that have them (Python).
