There is no specific forum for that. You can try your luck in the brand-specific section or in the general discussion. At own risk. If you have read everything about the topic you know what you are allowed to do. But you also know what QC is for. It's just for you to make sure the watch is the one you actually ordered and is working. If it has any flaws or characteristics you perceive as flaws it's your decision to make if you can live with those, ideally by putting in perspective what you're buying, at what price, and how it is pictured (magnification). If you ask the community, you'll likely get different opinions, but the important thing is your opinion. It's easy when you start with reps to want the best of the best, everything is idealised and you tend to want this idea of perfection. What you really like gets lost in the plethora of images and opinions floating in the forum.
I have this 5-digit sub, turns out it's a mid- to low-tier product, with a squeaky raffles bracelet, lost pip, but I like it a lot, it makes me feel good and I don't care what others see as flaws.
But I can understand you, I've been there, too, although I made QC on my own, knowing (more or less) what to look for, everyone's different.
Manage your expectations.
