Flaffy Industry practices, my dear, industry practices. As for policy, I heard they heard your voice, but it's Qidian, took them half a year to proceed to the next step, let's see when it'll come.
Also, it's not getting a little old. Before becoming vocal about something, you should do your own research. What is the business practices of the other giants in the translation sites? What are people used to? Now, you broaden your horizon, what is being done in a multitude of sites with subscription model, or you can just go to facebook and twitter, how much of your information is being sold? It's funny. The moment you enter the internet, your information is already a product being bought over.
The big translation sites has always used paypal as the medium to pay their translators and editors, to receive donations from fans. There are other methods, yes, but paypal is the most prevalent, not to mention patreon. I don't have any idea why do you even bother about your argument in this post. Paypal is proven, paypal is what people are used to, QI will add more functions, but it will take time, so they prioritize what is already being used in the industry.
