is there some more info somewhere about that flood? how many teams? how many submissions? how many unique? how much money G paid out?
And the spreadsheet is public [0], I counted 7 unique hoarded bugs (submitted immediately after launch) after deduplicating by patch commit hash. Then in the month following, another 9 unique bugs were submitted.
As for how much paid, I don't remember. Could be around $200~300k in total.
