Social network Reddit recently began blocking mobile visitors to its website while pushing them to download the official Reddit app, and it's fair to say that the move is not going down well with users. If you visit reddit.com on your iPhone today, you may see a new popup that can't be dismissed, asking you to "get the app to keep using Reddit".
If an instance has the most people and blocks those people from seeing your post, delays it from posting, or downgrades it as a source, it could easily be done. They have control over their own instance.
Yeah, but it would be pretty obvious they were doing it.
