Filtering out scam mails and deleting them does not hurt a scammer in any way, but wasting their time by sending fake replies does. As the amount of replies grows, the amount of time a scammer has to spend responding to e-mails increases. This bachelor project has created a revolutionary system that recommends replies that can be sent to answer a scam mail. This makes it very easy for users to waste a scammer's time and destroy their business model. The project has a unique adaptation of the Elo rating system, which is a very popular algorithm used by systems ranging from chess to League of Legends. A Google Chrome plugin was developed with user friendliness in mind, to let people reply to scam mails quickly. To gather replies, a crowdsourcing website, which also trains the Elo system, was set up. Finally, a Python server connects all the parts, allowing for cross platform communication.
