# 6.2 Prevention of Abuse and Manipulation In the process of contributing to the metaverse ecosystem to receive rewards, there may be instances of fraudulent activities to obtain rewards unfairly. Examples include exploiting vulnerabilities for illegal manipulation or using multiple accounts to gain more rewards. To prevent unjust rewards, CLEBUS intends to implement several methods. User identification data is converted into decrypted hash values and stored on the blockchain. Accounts without assigned unique identifiers will be restricted from using the platform, making it impossible to manipulate through multiple accounts. Additionally, minimum required actions for rewards will be defined in code to exclude meaningless or repetitive activities from the reward system. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
