Reddit uses the NSFW flag as bait to get you to sign up for the app. Any time you click on a link to such content, you are told have to install the app to see it.

Maybe this is a mobile only thing? I can view NSFW content on desktop (both old + new reddit) while being logged out and logged in without a prompt to download anything.

Thanks I'll have to try that, I think I've only ever used it on my phone. I recently encountered that app-wall and had even googled how to get around it and couldn't find any information on it.
