If you're not logged in and open up reddit.com on mobile, the first thing you will notice is a footer asking for you to open in their app, and your choices are "No", or a prominent "Continue" [1].
So if you click no, you're still not done, not even halfway on their dark pattern for getting you to install their app. When you now try to open a post it will stop the page, darken it and ask you to again open it in the app [2]. Now "Continue" means continuing to seeing the post so you click that.
Okay after twice as many clicks as necessary and 2 prompts you're finally looking at a Reddit post, but you're still not done! When you load in the post you will see a huge bottom footer _again_ asking you to open it up in the app [3]. And now you have the two choices and the worst dark pattern of all. You see a huge "Continue" button, which now means continue to open it in the app, or a really small link that says "or go to the mobile site". The thing is, is that you are already on the mobile site, and clicking that link just removes the footer, you won't actually "go" anywhere... So here they are tricking people to thinking that clicking continue will let you keep looking at the post as normal (as they taught you on the previous prompt), and by clicking the the small tiny link that is easy to miss, you will be brought to somewhere else. But the case is actually the opposite.
Reddits mobile page is just the worst collection of dark patterns I know of, in line with the fake download buttons littering shady sites. It's almost unusable now, and I'm sure that is their intention. Make the mobile website experience so horrible that you are forced to download their app so you don't have to spend half your time clicking away prompts.
