Perhaps a better approach would be to randomly replace links in your social media app with links to a random image of what you imagine to be a social media addict, or someone who has ruined their lives due to social media. Perpahs with a message like "This will be you in X years". Hopefully over time the subconscious parts of your brain will get the message. In your current approach, the signalling is largely aimed at the conscious part, which is usually not where the problem lies.
