Having only three examples, one of which doesn't even fit the criteria, seems a tad bit... hamfisted, shall we say? It would seem that what these types actually have in common is extroversion and intuition, not Te and intuition.
To confirm this theory we can make the prediction that your next stalker will be an ENTP. If that ever happens - good luck, but at least you have proven that extroversion + intuition strongly correlates with "crazy" (obvious really). If it doesn't happen however, this theory unfortunately holds no water and is undeserving of further scrutiny.
