Antipoints refers to a hypothetical currency that would deduct points or credits from a user's account for certain negative behaviors or actions. However, there are several synonyms that can be used to describe a similar concept such as demerit points, penalty points, negative points, debits, and penalties. Demerit points refer to a system where points are deducted from a driver's license for traffic offenses. Penalty points and negative points are similar, where points are deducted for rule violations in a game or competition. Debits are financial transactions that deduct money from an account, while penalties generally refer to punishments for breaking rules or laws. These are just a few of the synonyms that can be used to describe the concept of antipoints.
