I see, but the question is who needs to send anonymous SMS. You send messages to your friends, family, co-workers, etc you don't need to hide your face. The only group of people I see who may be interested is for marketing spam purposes. For example, I receive at home 2-3 calls weekly trying to sell me, swimming pools, insurances, solar panels, etc. They call less since we are now able to report them. With a website/app like your, I guess they will really enjoy it
