Reddit will warn you if a community allows NFSW content, then it will warn you again when you are about to see something NFSW. Many subreddits do not allow NFSW content and moderators will ban your contributions if they violate their community rules. NFSW stuff is pretty much an opt-in experience at this point, and that's fine.
