I don't really lose much if people don't know I spent that hour or two 
And if it helps someone, all the better 
If he's copy pasting, then it probably won't work too well, but if it does, hopefully it's something worth observing. I'd like to see something I made used somewhere. It would "honor" me, for lack of a term of lower degree.
I agree with you.
I think there are 3 types of people taking others ideas/works:
First are those who can't do that kind of thing, but they want everyone think they can. That's not serious...

A lie of such people not hard to recognize.
Second are those who can't do that kind of thing, but they need it in their work. It's not a problem for them to give credits to the author, but some of them don't want to, or just forget about it. That's too not very serious, but a little disgusting.

Third ones are most awful I think.

They
can do such job, but they just don't want to. Some of them give credits to the author, but most likely they don't. It's hard for other people to understand the truth.
I can give you examples, but i think you'll understand without them.
