I wrote a paper for a client. How to get paid?

Aside from shaming the client and making it impossible for him to use the paper by posting the essay publicly, there isn't much you can do. Since the business is mostly based on an honor code, if one party chooses to not honor the agreement, then you are pretty much sunk. Unless, you know the full name, school, student ID number, course, and professor's name. Then you can probably try to file an academic dishonesty complaint with the proper academic authorities. I have yet to see a writer successfully bring forth an academic case to a university though.

Posting the full essay in the free essay section of this website does nothing to harm the student. Did you forget that he is not supposed to submit the essay that you wrote for a grade? If the student has a good understanding of how the pay for paper game goes, he will have used your essay as the basis for a totally rewritten essay. He will pass plagiarism checks and he will be able to confidently tell his professor that he wrote the original paper, paying you to do the information research for him. Shaming failed ! Plagiarism complaint dismissed ! You should have gotten the payment before giving him the completed paper. Lesson learned on the OP's part I hope.
