Volleying is when two or more players hire someone else rapidly. Everyone benefits from a volley including the person that keeps, but their benefit is not received until they sell the tutor. The person getting vollied makes the least money due to the cap of 1,000,000 that can be received from being hired. The person that keeps and the people(s) that do not keep all make money, but it depend on how high they volley and how many people are volleying the person. If less people are volleying, then more money will be made by each person.
Farming is when someone fights/dances-off against someone 5 or more times in 24 hours.
