What two methods can a B2C company use to combat spam?

A B2C company can effectively combat spam by requiring CAPTCHA and requiring users to register to submit tickets. CAPTCHA helps prevent automated bots from submitting spam tickets by challenging users to complete a test that distinguishes between humans and machines. This adds an extra layer of security, ensuring that only genuine users can submit tickets.

Furthermore, requiring users to register to submit tickets creates a barrier that filters out potential spammers, as it requires them to provide identifiable information before they can interact with the support system. This not only discourages spam submissions but also enhances accountability, as registered users are more likely to provide meaningful inquiries.

While other methods listed, such as IP filtering or limiting ticket types, can help in managing spam, they do not combine the proven effectiveness of both CAPTCHA and user registration in directly preventing spam submissions at the outset. Hence, the combination of these two methods stands out as a strong approach for a B2C company facing challenges from spam.
