What a clown.

I looked at that website the other day.

A) Even to a veteran chart reader, the charts does not make much sense/useful.

B) Maybe there is an error in the data.

C) I would not base anything from those random charts. Some days it explodes and then totally dies. That does not make much sense.

D) And the line that is supposed to be "legit" users, is so tiny that you can't even see it moving (my guess it is the extreme explosions in the other line that destroys the read-ability of the lower line).

In Essence: The chart is more confusing than helpful.
