Here's how I'd answer...
1. How did you learn about Bitcoin?
On the Internet.
2. The purpose of trading on Bitstamp?
The same as the purpose of trading.
3. What is the origin of the deposited Bitcoins? If mining, please specify your hardware specifications and submit a receipt or an invoice for your mining equipment.
My bitcoins were deposited from bitcoin-qt without specifying inputs, so I have no idea of the origin of the specific bitcoins that I believed I was safely depositing on your exchange. I'm pondering a way to approximate the percentage of bitcoins in my wallet that are mined, but given the amounts moved back and forth from various bitcoin sites, always leaving the inputs up to the software, this would be a very difficult and extremely time-consuming research project that I'm not willing to waste my time on unless your fear of the thieving thugs that call themselves "government" is so great that you're going to block my money on the grounds of not producing a chain of custody for my bitcoins.
4. When and how did you obtain your Bitcoins?
Between early 2011 and the date of the last deposit to your site. How? Buying and mining... Are there any other ways?
5. What is the reason for your activity - depositing BTC, selling, withdrawing?
Trading?
6. What are your future plans and activities planned on our exchange?
Withdrawing all my coins and never doing business with you again.
7. Do you plan more of such withdrawals in the future? If yes, how many and why?
Yes. All my coins. Because of this bullshit that I'm replying to right here.
8. Which bank are you using? Please provide the complete address and SWIFT code.
The one that's already registered in my account.
