I interacted with 15+ people (got 20-30 "smiles") over a 1 month period and 100% were deemed to be fake profiles. Save your money. You can read the profiles and see the exact same text in multiple profiles and many pictures of almost celebrity looking people. I just started reporting them to try and help others. Worst spend of $100, glad I only did 1 month!
Tip for consumers: Unsubscribing is very difficult, doable but not easy
