Students order less essay in 2012 coz they have less money and iPhone cost more than before.
Other reason - Kenyan, Indian, Pakistan, and China fraudsters with anon emails (gmail, hotmail, yahoo, tc.). They pollute chat boards, Facebook, Google, and use many fake names. Students contact them and then have to chargeback and contact legit companies to fix their plagiarism and simple errors. On this forum there is dozens of scam artist from Africa and other non English speaking country.
If you are student and some 'writer' contact you to help, get his phone number first and talk to him. Then you see he/she is from Africa, Paki, China, or India. They moved from lottery scam to essay business.
