An account is usually marked as suspicious or inactive if:
no posts have been created for more than 90 days.
follow-unfollow activities have been detected on this profile.
post likes have been disabled on this profile.
the profile meets certain criteria that we have identified in other fake accounts. (e.g., no profile picture, generic bio, unusual follower/following ratio, and unusual like and comment metrics)
These activities are generally only found if they have a significant impact on the account or if they have occurred over a long period of time. If these activities lie longer in the past, then they are not displayed here. This process is mainly based on machine learning algorithms and is dependent on the influencer's metrics. (location, language, etc.)
