Our reasoning is already on the page, so I will not repeat it here. We do our best to judge by the user written descriptions of statements. Unfortunately sometimes the outcome is not as unambiguous as we want. I guess that is why lawyer-talk evolved to be so convoluted. This particular case does not meet the unambiguity criteria we set ourselves.
Everybody got their full bet back, including the original submission fee. We could choose to select one side and earn a significant commission, enough to buy a nice laptop these days, but we didn't.
I respect everybody who thinks that we didn't judge well enough, but scamming is a different matter. I hope at least some of the bettors understand and respect our decision when the dust settles.
