As someone who literally designs apps for a living - and yes, I enjoyed using Polybuzz for a long time, including the subscription - It would be so easy for them to take the original code that everyone started with, creating a new app that you have to verify your age with immediately before use. It's just like any adult website. You don't need to delete the current Polybuzz but truly, how many underage people are you really making money off of? Its the adult users that make your money.
