Honestly people, why blaming the entire insitution for your personal bad experience? It's like if you met a jerk at the church would you blame Christianity for your lack of luck?

If you repeatedly meet jerks, then maybe it needs to be explored why, there might be a reason you attracting jerks. Or it's just bad luck and you might need to spend more time on it etc but I don't see why is it online dating fault? These are not some people cooked up in cyber world, these are same people you might meet in the real world. You just have more options

Also if you were matched up or contacted by a wrong match or an idiot. It doesn't mean you must date that person. You have to exercise your own judgement. It's not websites fault that we end up dating wrong people

I dated plenty of wrong people in my life. It never occurred to me to blame anyone.
