A slight digression but lol, this is my experience with all of the bug bounty platforms. Reporting issues which are actually complicated or require an in depth understanding of technology are brickwalled, because reports of difficult problems are written for .. people who understand difficult problems and difficult technology. The runarounds are not worth the time for people who try to solve difficult problems because they have better things to do.
At least cloudflare has a competent security team that can step in and say "yeah, we can look into this because we actually understand our whole technology". It's sad that to get through to a human on these platforms you have to effectively write two reports: one for the triagers who don't understand the technology at all, and one for the competent people who actually know what they're doing.
