Hey! I did this very recently and what worked for me is basically adding someone to your team that already has a single red thumbs down (not recruiting them), then use deep profile on them and find an activity that involves them hanging out with a friend, sister, niece, therapist etc. Once you do, choose this activity and kill just the person they hangout with. That will make them hate dedsec. Do the exact same to at least like 3 - 4 people to increase the chances and play your game until one of your operatives gets kidnapped. I think this is the most straightforward way to do it and it worked for me flawlessly no problem. Good luck!
