Since OTPs confirm ownership of the provided contact details, follow-ups become more effective and reliable, which in turn improves the quality of leads.
CAPTCHA is good for basic protection, but it can frustrate users and is sometimes bypassed by bots. However, the OTP method confirms real contacts and offers stronger spam prevention
