This is taken from our help center:
These accounts follow, play, like and repost sounds across the community in order to appear human. Our Trust and Safety engineers work hard to detect fake accounts on the platform, but cannot always remove them before they have the chance to make actions on the site. When they are removed, any reposts, comments, follows or likes they have made, will also be removed.
Please note: We do not have the technical means of reverting, or adjusting, play counts.
