Mentza is a democratic platform, and sometimes that means that there can be disruptions to your circle sometimes.
The initiator of a circle can use the Force Mute option in the event of a disruptive user in their circle.
The initiator can mute a disruptive user by long pressing on their profile image and tapping Force Mute. The person being muted can request to be unmuted, which the initiator can accept/decline.
