Their large clientele is all sorts of spamming services. I receive tons of messages daily (currently ATT but Sprint before) for different type of products and services, mostly work by completing surveys. Everytime I trace number down - its Twilio. And their spam complaint team never answer to my complains, so unfortunately as long as spammers can use their services, they will be making money.
On the good side, I use their services anytime I need to "confirm my identity through a text message".
I think its impossible to determine whether a cellphone is a real number or Twilio number so it always works! I have a cash prepaid Visa card that I can purchase a Twilio number for $1 and have a text message with confirmation code come to my throwaway email address. Well worth a dollar for almost complete anonymity!!
- jsjohnst 10y agoIt's not impossible. It's quite easy in fact to determine if a number is a real cell phone or not by doing an NPAC lookup to see if LNP is applicable (if so, you just check the service provider type, if not, a simple check of the NANPA allocation would do). Lots of companies provide it as a service. Just most places don't check and blindly try to deliver to whatever number you provided.
