Hi. I am interested in your services. But I have some questions: 1. How many times do you allow the replacement of the proxies? (Instagram Proxies) 2. What is the difference between Private Proxies and Instagram Proxies? (Why I should buy Instagram Proxies and not Private Proxies if I am into Instagram Marketing) 3. Each Instagram Proxies which you're providing are totally new or are they used before? 4. How unique will be their sub-net and all the other metrics which can save me from Bans? Thanks.
