first of all, they ban accounts based on several algorithm, i can not exactly tell you why, but i think you can follow the logic the find out yourself. first, email or phone, they have a system detecting phone and email spam, so did you verified the account with public service? if not, next, ips, ips is important, and try to avoid datacenter ips, if some crazy play shit in your ip set, you got fucked as well. if your own residential ip, is it too many accounts using it? then, fingerprinting, if you use real phone, ignore this, if web-based, and you have too many accounts there, 100% they will get you, at last, someone is reporting you for your content, they will not tell you, but when they got some reporting, they can ban you without any warning. My accounts got ban with rand 2%, after a week warm up, they are rarely banned.
