Because he was politely asked by the owner of that forum and the chart creators to not share their charts on this forum. And he agreed not to. Doesnt matter if you dont see a problem with it, I'm personally indifferent to it. But its simply the fact he was asked more than once by the chart creators and forum owner not to share their charts, as those charts are made exclusively for that forum. And he goes and does it anyway, despite his own word. Its a matter of respect for peoples things and the work they put into them, simply.
