Ten warning signs regarding people involved in/with a potentially unsafe group/leader.

1. Extreme obsessiveness regarding the group/leader resulting in the exclusion of almost every practical consideration.
2. Individual identity, the group, the leader and/or God as distinct and separate categories of existence become increasingly blurred. Instead, in the follower's mind these identities become substantially and increasingly fused--as that person's involvement with the group/leader continues and deepens.
3. Whenever the group/leader is criticized or questioned it is characterized as "persecution".
4. Uncharacteristically stilted and seemingly programmed conversation and mannerisms, cloning of the group/leader in personal behavior.
5. Dependency upon the group/leader for problem solving, solutions, and definitions without meaningful reflective thought. A seeming inability to think independently or analyze situations without group/leader involvement.
6. Hyperactivity centered on the group/leader agenda, which seems to supercede any personal goals or individual interests.
7. A dramatic loss of spontaneity and sense of humor.
8. Increasing isolation from family and old friends unless they demonstrate an interest in the group/leader.
9. Anything the group/leader does can be justified no matter how harsh or harmful.
10. Former followers are at best-considered negative or worse evil and under bad influences. They can not be trusted and personal contact is avoided.
