Rin truly is a master baiter (for donations). How she turns a random zatsu stream into getting thousands of dollars is a skill I will never understand.
She literally just started talking about wanting a Blahaj Mahal and putting up a fake donation bar for 1,000,000 dollars. Then she starts off by wondering how much money she would need to see a single pixel on the bar...tempting her viewers to start throwing her money to find out. And they did. A lot.
Which then transitioned into her throwing up a boss health bar overlay where donations take down her health. Then she made the boss her biggest whale and pitted chat against him. They donate to kill him and he donates to heal.
This fucking brit, I swear.
