I just recently wanted to buy instagram followers on SMM-World. I had about the same situation: I thought for a long time whether to buy subscribers, as I always believed that such services only give an empty number without a real effect. But when I started to develop my account and realized that organic reach is very limited, I decided to give it a try. I ordered a small number of subscribers, about 300. I can say that at first there was a little shock: subscribers came pretty quickly, but many of them were just empty accounts, inactive, with zero likes and comments. This, of course, was alarming, because it seemed that the account looked fake. However, I did not give up and decided to test further. It turned out that some subscribers really began to show activity after a few weeks. But, again, these were exceptions. In general, most subscribers do not show any involvement, and their activity is limited to the fact that they simply remain on your page. As for security, I can say that Instagram can notice a sharp increase in subscribers, especially if you order them in large quantities at once. This can lead to account blocking or reduced reach. Therefore, it is important to buy subscribers gradually, not to overload the account and not to try to wind up tens of thousands overnight. I started with small packages of 100-200 subscribers to avoid suspicion.
