I bought skin manager from him few months ago.
1. He was not able to send me client side files, instead he copypasted over 1gb of textures from other servers and I had to dig in his trash and found like half of skins. Many skins on client side missing parts like helm and etc.
2. His java code is very poor quality. Asked him to fix userinfo integration and he was not able to, so I had to fix his own code. His sql queries were causing my server to lag and crash as well.
