I still don’t understand the concept of online dating.
What’s so hard to make friends through hobbies, and from there develop your relationship from? It’s far more likely you will find someone compatible if you are already friends with them first, than trying to form a relationship with a stranger that you literally know nothing about except for what they advertise online.
Of course, this would require people to actually go out and meet people. Maybe this is what they’re afraid of in the first place?
