Snake, dont take it so harsh on him. I think he makes a good job helping people with his way of doing.
It dont seems like he copy paste, if you really want him to i guess he could write that he got the knowledge from this for example.
But i think thats just dumb, instead of directly helping the user. Of course it would be handy to show that topic or other helping offical topics for support.
But of course you was first done. But he had a more filled content in his post. Why are you mad, you both knew the answer and got helped the poor fella with his problem 
But in the end, what he is giving to the user is just knowledge he aquired by being on this site.
He just try to help others. Why bash down on him. He isnt copy pasting.
I dont see why he need to add sources to everything he post, because its mostly just common knowledge.
PS: I see you post right after each other, could be he was in the middle of the post before you posted and you posted kinda the same time?
