With online money transfers or via Paypal, you could potentially attempt to scam someone via false claims of fake goods or services, or potentially with a false claim of being able to direct a person’s money to an account of a fake organization, or fake charity, or fake government.  You could potentially attempt to use another person’s Paypal account to get money, or attempt to create a fake Paypal account to receive money from another person.

Well, there’s a lot of online scams that focus on convincing someone to send a small amount of money to an untrusted person, who’s not necessarily from the area where they live.  It’s generally done by getting someone to fill out a form online, which looks official and asks for personal information.  Or by emailing them, with a message that seems to come from a company or government agency, that will ask for information about bank accounts.  
The person may think they’re in some way involved in a legit company’s process, or want to help with a legal matter.  They’ll be told to send money to a third-party that will assist with some matter.  But when they receive the money they’ll find out it’s been stolen from them.
