I don't see #4. . Maybe I'm missing something. :)

I will give my guess though.

1. Papa-Pepper - B. The wild animal whisper.

2. American Homestead- C. The infamous banned you tube star.

3. Shalomacres- D. The maker of fine meats.

4. Whoever you are - A. The little Smokey Lego Block Builder.

I'm guessing 4 is Randomstuff.
