Because even a phone number is not enough to keep out bots.
Some VoIP providers do a PAYG model, so you can choose from any number of phone numbers, regional, local landlines or from mobile numbers for free and only pay when you make a call or answer their answerphone.
Now obviously Twitter will send text messages so you never incur a cost from the VoIP provider.
So how does a phone number solve bot activity?
- shmatt 5y agoits a cat and mouse game. lately I've found many websites show an error when I put in my Google Voice number for sms verification I don't know how the implementation works, if theres a way to check for virtual vs. real number, but some sms verification service provider seems to have successfully implemented a filter on Google Voice
- koolba 5y agoDon’t you have to seed the PAYG account with a non-zero amount of money to initially get the number? Even a few dollars multiplied out becomes a significant spend if it’s a unique number per bot.
