I used to run a website called roboshout.com... at one point was making almost $1000 a week... I used Stripe to accept payments. The user could send/receive anonymous texts, send 1000 texts, custom robocalls etc... 2 years into a happy partnership with Stripe and decent income... I got a letter pretty much saying the same thing except it was in regards to "telemarketing". Lost the API and my website functionality overnight with no warning!
