For example, in a survey of parents who are targets of alienation, Baker and Darnell4 found that targeted parents reported that
alienators interfered with parenting time (e.g., scheduled appointments or
frequently called during the other parent's parenting time), interfered with contact with the children (e.g., intercepted phone messages or email), interfered with symbolic contact like gift giving (e.g., threw away gifts or sent them back), did not inform them about important information (e.g., school activities, doctor appointments), threatened to take children away from the them, and formed unhealthy alliances with the children such as having had their children spy and report back information to the alienating parent, or sending cell phones with children to call the alienating parent from the target parent's home.
