If you want to Opt-Out of the new Interest based targeting or Personalized advertising on Reddit, they’ve made the process very simple.

1. Simply visit this url: https://www.reddit.com/adsprefs
2. Uncheck the box marked “Show me personalized ads from Reddit on this browser”
3. Then click “Save Options”

The opt-out option is cookie based so it works on a per browser basis. If you opt-out on Chrome while logged in and you log out then continue to browse Reddit your preferences to not be targeted with personalized ads should stay.

This also means that if you clear cookies or use a different browser you’ll have to reset your preferences. Because the system uses cookies if you want to have one account that you opt-out of advertising for and another that you leave opted in and you login to both using the same browser then you’ll notice the last action in the browser is what counts.

User could alleviate this by using one browser to opt-in to the targeting and one to opt out of the targeting.
