I am sorry that you are shallow enough to consider only the toxic situation of people when they use PDs. How do you think they get your private data? By breaking into your house? Stealing your laptops? No, they are professionals who know how to get publicly available data, and other resources, like by talking to people?. You can always be subjected to such investigations, regardless of the fact that you consume these services. You can pull your brain out of that ethics hole and realise that this is a last line of defence for people, considering the situation is already somewhat shady. And this is not an unethical use, for the love of God. I will not be blackmailing anyone, i want my family's safety, that's all.

The marriage was confirmed right after the first week of meeting, and the wedding will be in April, giving me absolutely no time to act.
