Thinking about this some more, posting it at 4 AM-7 AM Burger time is also a terrible time to get eyes on it. Yeah, you'll get burger eyes on it later, but letting it sit and slowly drip out doesn't do much for getting significant attention, and then there's a risk that everyone will disregard it as late, insignificant news by that time. And then they actually logged in to check the damage at 12 AM - 3 AM Burger time.
It makes me think that whoever posted it, posted it at that time, because it was just the best time for them personally. Because while I agree it was done purely for malice, the timing isn't the best for malice purposes, for the same reason it's not the best for attention purposes.
It makes sense if someone in the GMT + 8, 9, or 10 timezones posted it before going to bed, and checked the thread after finishing work in the afternoon.
