I'm fine with the ruling either way as I don't purchase lewd figures. john shouldn't have to be concerned about the thread locking due to borderline figures being posted. NeoGAF ruling has spoken and taking precautions to keep the community alive is a fair move.
It's definitely on a case-by-case basis. A BRS figure would be observed on its own standing as well as a Lilith figure (not according to "how sexual or not" their source materials are). In other words, it would be safe not to post any lewd Lilith figures
I don't think I've seen a "lewd" BRS figure before (aside from maybe the GoodSmile Black Blade which I don't even care to post, knowing the character's age or not).
