Oh, it most definitely is scummy. It’s no news that Tinder does not care about people well-beings. Actually, they want you to get stuck to the platform as long as you can; if everyone was finding their partner after a week their platform would not be profitable anymore.

On Tinder it would not be in the same context that what you experienced. In OKCupid it’s part of the rules that you can send messages without a match. So people are OK (I guess) with it. On Tinder it’s going to come as unexpected and unwelcome. You will start with a disadvantage. Unless the woman is only interested in money (if you can spend $500/month on an app then you are probably among the wealthier half of the population).

I would say it is this way because it takes a big effort to crunch all the patches that have been made thus far and make an easy-to-read summary out of them.

It’s not something that comes for free. You need someone on the job.
