Some guys have the same issue , Instagram keep asking some account phone verify again and again. I have do lots test. 1. Change Password 2. Change Email 3. Different Setting with every account. 4. Change phone's country to verify. 5. Buy real SIM card to verify instagram account. 6. Some account do nothing after phone verify but still got phone verify again. 7. Change Proxies Address. and etc... Now I found it's proxies problem Because I have lots accounts and lots proxies, some proxies are with the same C range(61.79.128.*) when u do lots things (follow , like, comment) with the same C range. It will keep asking phone verify. Anyone have other issue ? we can discuss about it. I have running more than 5000 account now. BTW, how is selling the proxies with all different C range? I need lots different proxies.
