I've had textnow for years, and I've never had any problems, never done anything illegal, unethical, or harmful with it. In other words, I've never "violated the terms of use." However, I just got locked out of my account with that very error message. Lost a bunch of messages I needed. But ok, must be a glitch, these things happen. Made new account, it's been not even 24 hours, I texted 2 people about dinner plans, and now I'm shut out again, same thing. Why don't you want me to use your app?
