Until recently Mr. Community had one single reputation point, you can see it in this old screenshot:
Now it has over 2K reputation all of a sudden.. what has caused this? Has it affected "real" members as well?
There may be a capped reputation incentive (at the moment we are thinking you can get up to 1000 points 2 at a time for good edits)
Not sure if this is indeed implemented! Given the large increase of reputation, I guess the team might have been using unregistered users to test. On the other hand: at the time of writing this, on Super User the reputation was still 1, despite approved edits.
If you check his reputation graph, you'll see that his rep seems to come from Community Wiki posts.
