"Unfortunately, RawGit has also become an attractive distribution mechanism for malware. RawGit was meant to improve people's lives, but jerks are increasingly using it to hurt people.
Since I have almost no time to devote to fighting malware and abuse on RawGit (and since it would be no fun even if I did have the time), I feel the responsible thing to do is to shut it down. I would rather kill RawGit than watch it be used to hurt people."
