They can come up with early morning spoilers. Not with a list of every Daily Prize almost from the start. That can come from any or every server.
It seems you are conflating two separate issues, that for the Soccer Event have worked in tandem, but have nothing to do with each other.
List or no list, we've had advance notice on Daily Special for every Event I've played so far. These advanced confirmations, "Spoilers", have come from players on the Thailand server.
For the Soccer Event, we've had an unconfirmed list, source unknown, of the upcoming Daily Specials that's been making the rounds since late June. Because of the Spoilers coming out of Thailand, we've gotten early confirmation that the Daily Special predicted, will in fact occur.
Without the list, we would still have the spoilers from Thailand, and without the Spoilers from Thailand we would still have the list of predicted Daily Specials, that still would have been confirmed, just many hours later, when they finally appeared live.
Clear as mud?
