I can’t speak to the average quality of submissions, as I’ve only made one to HackerOne myself iirc. I don’t even consider myself good at coding or aware of how to file a bug report or bounty submission. I reported that on iOS Coinbase app, that if you were on a VPN, the Coinbase app PIN simply didn’t exist anymore, and did not appear in the settings as enabled either. I included a full video of this occurring and it seemed reproducible. The Coinbase person said that this was not an issue because you would already need access to the physical device and know the iOS passcode; relevant to this is that at the time (2021) and maybe now, the Coinbase iOS app didn’t hook the iOS passcode for access control, like Signal or other apps do, but instead has its own app passcode. The fact that this was circumventable by adding and connecting to any VPN on the same iOS device seemed like a bug in the implementation, even if it is the code working as written. The issue was closed and I lost 5 HackerRank I think the points are called. It felt very hostile to my efforts that I lost points, since I don’t think that was justified. Perhaps that is just how the platform works for denied bug reports on HackerOne, but I have no way of knowing that, as the Coinbase report is the only time I used the platform.
They have a concept of "rando" as you can see above. They don't usually say that out aloud.
Basically if you are new, the reviewer thinks "oh, a rando" and in his mind he has already downgraded the severity a bit.
It's unfortunately a kind of cartel at this point. Not full fledged and out but a low key cartel. They have a circle of friends whose csrf would also get better valuation. It's a sorry state.
