I wish he would just say what it is happened already!
Chris keeps saying that he's in the worst financial situation, that someone took advantage of him, that it's not his fault... but he refuses to just outright say what it is that's bothering him.
He's desperate for money, but not desperate enough to spill the beans, so instead he just expects people to blindly donate to him because they just have to trust him. This has lead to the majority of people assuming that he just spends all his money on Lego, if he would just say then he could put an end to these rumourss and maybe even convince some people to take pity and donate.
And he says it's not his fault, so it's not like it'll be embarrassing for him to admit what happened.
Hopefully he will actually explain what happened at some point, until then my best guess is that Barb fucked up, maybe she has a gambling problem... and she's been screeching at Chris and manipulating him to beg for money and sell his toys. Do that thing he does to magically spawn money from the internets, but also tells at him to keep her gambling addiction a secret.
