Since the blockchain is decentralized, there is no real "authority" to suppress adult content. There is an option in each individual's "Settings" to control whether content that is marked NSFW (Not Safe For Work) is displayed or not. There is quite a bit of such content here, but sadly, much of it is simply copy/pasted from other sites rather than being original. Most of the original NSFW that is here is fiction.

Love the caption to your photo... 😂
