Wtf is wrong with you? Someone shares a project that they have done for fun and enjoyment and you publicly call it "awful" without any explanation. Would you do that to someone in person when they show you something they've done? The least you could have done is explain what you don't like about it and how you would have made it differently to make it better. This kind of behavior is something that pisses the hell out of me, and to be frank it also keeps me from sharing some of my for-fun projects. I don't want to spend a lot of time documenting them and writing a blog post to hear some dumbass call it "awful" without explanation.
