It's this really...awful cycle, man. It reminds me of how Korean/Japanese idols are taught to be super nice and sweet to fans who they might not like or even feel uncomfortable with. It's...an attempt to make everyone feel special and happy. It's coddling, but for adults. So they get it in their heads that you DO like them and see them as a friend as opposed to being just another fan. If you can make them feel special or loved, you can keep getting their donations or selling them merch. They'll keep watching the content. It pacifies them and keeps them from telling other people what a bitch/asshole you really are (in their warped mind).
