Even after getting hit and penalize by many Google updates, i'm happy to know that you are still able to take more update hit, 3 Cheers for you. If you really don't want to get hit, stop asking this type of question "
where can i get quality backlins?" Don't do this with your SEO Profile
Ask: "Where i can share Quality information?", the place which requires you to give some quality information from getting approved for the posted content are the trustworthy site to get reference from. Always try to give more information instead of just for the sake of Linking.
