280gou has more of a problem with western mugen users than Vin specifically
First, he got mad when he found out there was an edit of his Goku with no permission uploaded to a western site
I can't remember if he asked westerners to stop but he went on to say his future characters will be password protected on a new storage account
Fast forward to now, he made a new Gohan character after a lot of work and locked it so only Japanese users could access it but it got leaked anyways so as a result, all his accounts are private and now he's thinking about quitting.
