Effective Spam and Fraud Prevention Strategies

Preventing spam and fraud requires a combination of strategies tailored to your app's needs. Using CAPTCHAs is a popular option; however, the speaker emphasizes the importance of selecting a suitable CAPTCHA, suggesting alternatives to the notoriously frustrating Google CAPTCHA. Methods like rate limiting can also be effective, where actions from specific IP addresses are restricted after exceeding a threshold, making it harder for bots to overwhelm a service. Additionally, integrating services such as Stripe Radar can enhance protection by scoring interactions based on user behavior, thus filtering out potentially malicious activity.
