The chatrooms of all the popular chat sites are full of nicks that are computer programs called chatterbots that pretend to be real persons users of the chatroom. A chatroom may be supervised by employees of the site that keeps it. This or these operators may read what a real user sends in private or public inside the chatroom. Any operator can bypass the program of the chatterbot he wants if he considers that to be necessary to improve the performance of a nick when chatting with the user. The chat owner may hire the services of people who will keep electronic mail with the users that were seduced during their visit to the chatroom. The hired people will pretend to be one of the persons who was using a certain nick during the virtual meeting. This is a well kept secret in the Internet and there are not any kind of literarure on the matter which speaks in the way we do.
