Op is offering something which will do him some good by getting some money, but it is harming the some one's future. They will get their assignments done by paying some money but when in real exam, they will just fail.
Plus, if the institution comes to know of this, they may take disciplinary action against the student too.
In the past I have observed many people came with similar services but not seeing anyone sustaining. Probably parents and institutions might not prefer availing such services.
I agree with you 100%
This is for people who are too 'busy' to do their assignments.
I have a couple of friends who study in the U.S. who have a hard time balancing assignments and work.
This is for those people.
I highly encourage people to do their own assignments and gain knowledge by themselves if possible.
