This is why many apps/sites require a phone number to sign up.
- yomlica8 3y agoIncluding the vast majority of free email providers these days. Of course, there are tons of SMS verification services in existence already for exactly this reason. Although I haven't heard of a SMS rental service like this.

- costco 3y agosmspva.com does exactly this. Phone verification (assuming you enforce non-VOIP and block certain countries) raises account creation costs by a decent amount, email verification not so much. The sad reality these days is that a T-Mobile phone number, a Comcast IP address and an outlook email doesn't mean someone isn't a bot, it means they spent a few dollars for a proxy and an some verification services. Which is why I think that behavioral indicators of botness and not just user agents and IP address whois are increasingly important in detection.
