Info poisoning goes back to the garden. In Gen. ch. 3 the "serpent" -whoever he was- lied to Eve by adding one little word to God's command - the word "not". Sounded good to Eve, who used the lie to rationalize something she wanted to do - and without checking with Source, the Father which she could very easily have waited to do - she acted on her desire to believe the lie.
Serpent - poisons the mind - deceives and casts out lures.
