So does Pornhub's bug bounty program include some number of years of free paid membership along with financial bounties? Kind of a "treat us right and we'll let you treat yourself right" kind of thing?
If you know enough to be able to pull off hacks like this, you surely know enough to get more of this kind of thing than you'd have time to watch in 10 lifetimes. I doubt that such a "reward" would be very appealing to those who participate in the bug bounty program, and it'd honestly be a sleazy business proposition, which would harm the professionalism of operating a successful bug bounty program. And yes, I'm completely serious.
I'm glad you were serious, because frankly I wasn't. I'm sure there's more than enough "free" porn out there for just about anyone's taste, so I doubt that free accounts would be a significant incentive anyway.
