I think a few of them have honest intentions, and want to help. VERY few of them, but still.
bottom line is, it's a business for them, and a scammy business to boot. The scam artists give the few good ones a bad rep. They will make much more money off of you to give you false hopes, and have you come back time and time again, asking why and when things will manifest. Why are things going in the opposite direction, etc. And that's most of their objective: money! Not whether or not you end up with the person.
Some honest ones will tell you to let things play out and not obsess. Trust your own intuition first and foremost. And also accept responsibility with your own actions. I have been my own worse enemy when it comes to overreacting in my situation and pushing POI away further.
