Those who have exited a cult but need help adjusting to life in normal society. Friends and family with a loved one victimized by a cult. People who have been under the influence of cult mind control fear X-members and opponents of their group. This is because cult leaders vilify opponents for the very purpose of keeping members away from them. This fear works the other way, too.
Former members are often afraid to speak out for fear of reprisals from the group.
This is not paranoia - members who leave and speak out are seen as traitors. Such people endure unbelievable character assassination, harassment, and sometimes have a nasty habit of turning up dead from some 'accident'. Despite the resistance and danger, some who have broken free from cults establish outreaches to their former peers. Some outreaches in various parts of the USA and other countries have found that an answering machine with a recorded message effectively counters the fear of cult members by allowing them to hear the message without having to reveal their identity. When they are ready, callers can and do leave a message of their own seeking help.
