All trolling aside honestly I don’t see the issue with this.... obviously there is a difference between stalking and using the app to join clubs/communities and meet people in person.
I joined a hiking group on Meetup 3 years ago to meet people (not necessarily romantically; just to meet like minded people who enjoyed the same outdoor activities as me), and ended up meeting my significant other on a meetup. We’ve been together 2 1/2 years now.
There is nothing wrong with leveraging technology to locate other people, romantic or otherwise, that you might want to develop relationships with.
Just don’t be a sicko. Same rules of normal human engagement.
