The Jita Burn event is once more in full swing or is just finishing, not 100% sure but it was active over the weekend that just was.
The kill roll can be viewed at zKillboard here and it currently shows at least 500 billion ISK worth of damage, however the Admin Note states:
This campaign reflects only kills happening in Jita, it doesn't count the surrounding systems, and it only includes the kills that zKillboard knows about.
These losses include both the attackers and those being attacked in Jita but still just looking at some of the losses a lot of people unwisely decided to ignore warnings or were just oblivious to the whole event.
And they paid for it.
