I agree, but just to play devil's advocate if I discover a bug, disclose it, then tell all my friends to also file a report before it is filed they'd have to honor multiple bounties.
I, too, am frustrated that I've read far too many stories about someone reporting a devastating critical exploit and all they get is "this is a dupe" back without further explanation. Makes one paranoid that employees are working with someone externally, back dating their bug reports, and splitting the bounty.
You'd probably violate the agreement so you and everyone else technically wouldn't qualify and would be committing fraud. That said there are other options, such as splitting the reward for a vulnerability amongst those who report it (even the dupes). This would incentivize people not to disclose the vulnerabilities while keeping the payouts static.
