Well for chat its showing users online that arnt online. I know for a fact that Speed Freak said he was off for the night yet his name popped back up. Basically showing a whole bunch of people online when they are not, it started with Rio we saw here name a few minutes before she came on. This happened at 9:09 EST, any users below that werent on at the time can you please comment below saying so.
As for Pokebase, Meta, and RMT, they are showing the wrong times. Giving dates that haven't happened yet. (Oct 28)
From Mew: Top is PokeBase, 6th is Meta, 7th is Battle Subway.
