In that case, Reddit states 'to view posts in r/*** you must continue in the Reddit app or log in'.
This forcible action has annoyed a lot of netizens. It appears that the content is not blocked for all mobile users, but only a section of users. The screenshot below (on the left) shows the prompt that mobile users may get when they open a page in a mobile browser without being signed in. The first scenario happens on the desktop and the second exclusively on Reddit when using mobile devices at the time of writing. Or, the content may be blocked and you may get a prompt to either sign in to an account or use the official Reddit app to access the content. If you click on a link that points to Reddit, one of two things may happen: the actual page on Reddit may open right away and you may read the original post and the replies. It is not uncommon to find Reddit links in the results of Internet searches, in chats, emails, or by subscribing to domain feeds on Reddit.
