If I am suspicious I always ask the buyer straight out if this is academic work, or work for a class. They usually tell the truth. Then I tell them:
Fiverr does not allow services to be offered that involve helping students with academic work.
Taking part in doing someone else’s academic work (which will likely be submitted as the student’s own work) or requesting academic work to be done for you is unethical since it violates most schools’ Honor Codes and constitutes copyright infringement. Fiverr does not allow this type of fraudulent activity, and it will not be permitted on our platform.
Since it is against Fiverr Terms of Service for sellers to do any academic work, I do not want to take a chance on losing my account, so I cannot do this for you.
