An idea is a concept or mental impression. Very often, ideas are construed as representational images; i.e. images of some object.

The capacity to create and understand the meaning of ideas is considered to be an essential and defining feature of human beings.  more from Wikipedia

Spambot

A spambot is an automated computer program designed to assist in the sending of spam. Spambots usually create fake accounts and send spam using them, although it would be obvious that a spambot is sending it.
