Yes. You don’t have to worry about investing in authentic accounts, follower count, likes, comments, and views. The problem starts if they are fake or automated stuff. The Instagram algorithm might suspend the profile indulging in such activities. But there is no risk with genuine marketing practices. Real followers, genuine comments or likes, and views from the audience from a similar niche are legitimate and acceptable. Of course, some people can discourage you by talking about IG policies. However, you must know that those are rules and not laws. Hence, it is safe to work around them.
On top of this, buying real followers and engagements cannot be a threat. Even big brands, businesses, and celebrities follow this path to increase their visibility and dominance. You also need to resort to these, especially if you have business or monetary interests. Others judge your profile by looking at all these metrics. When they see your long follower count and higher IG likes and comments, they get convinced to collaborate with you. Just ensure that you maintain the right balance of followers and engagement rate.
