What is the point of such subscriptions on Instagram if you still unsubscribe sooner or later because you do not know this person and you are not interested in his life, what is more, important is to have contact with technical support. Do you know how to do it? If not, I can advise you on the instagram customer service blog with which you can contact technical support at any time, which will help you solve your problem. Once my account was blocked, I wrote to technical support, they said that they did it by mistake and removed the ban from my account, and if I had not done this, no one can guarantee that Instagram would have noticed it and removed the ban.
