Answer 1

Misha

Answer 2

Certainly looks like javascript to me. Though it's odd that there's an infinite loop at the top:

for (;;);

Answer 3

Yep, just JSON, though as others have noted the infinite loop at the top is troublesome. Here's what it looks like cleaned up, courtesy of jsbeautifier.org:

Answer 4

The infinite loop is a way to restrict access. For more information, see fearphage's answer to a related question.
