I saw the official reward standards for the reporting channel of a certain exchange—$20,000 per person!

And the result? I didn’t get anything at all.
What’s even crazier is, when I checked the list of winners, every single one had a gmail address. I sent my report using outlook? It was directly bounced back.
Someone in the group did manage to send it successfully with outlook, but apparently the reward still hasn’t shown up.

This whole thing really makes you wonder: does the prize pool only recognize certain email providers? Or do some email addresses come with a built-in buff?
The event rules are clearly written, so why are there so many hidden tricks when it comes to actually carrying them out?
