Exactly. Imagine if Reddit's transparency report included a fat canary. Something like:

The data for the following users (as of December 31 2015) has not been subpoenaed:

  /u/mike_pants
  /u/the_starship
  /u/SlimJones123
  /u/n3rdopolis
  /u/mrbabyman
  /u/GreedE
  ...

Individual users could determine if they've been the subject of a subpoena and I suspect that kind of cleverness wouldn't impress a judge.

Take it a step further and you could say "since date 20xx-xx-xx until now" for each user and really piss off a judge with your cleverness. After all, youre not saying when a user's info was subpoenaed, but the range of dates when it wasnt.
