Generally you should only see content marked as NSFW if you:
- directly seek it out. For example, you type in the name of an NSFW category
- enable NSFW browsing from your account settings (it is disabled by default, but will activate if you upload an NSFW piece of content on your account). You can double check your setting here: https://itch.io/user/settings
We have strict requirements on classification and filtering, so if something is showing up in place where it shouldn’t be then it should be reported to us.
Can you please share where you came across the content you’re concerned about?
