It is my understanding that to "cyberstalk" means to engage in a course of conduct to communicate, or to cause to be communicated, words, images, or language by or through the use of electronic mail or electronic communication, directed at a specific person, causing substantial emotional distress to that person and serving no legitimate purpose.  You indicte here that the claim is true. That defense is used in a lawsuit based upon defamation. Here, I do not think that it matters if it is true or not. If there is no legitimate purpose to the communication then it can be considered cyberstalking.  I would speak with a criminal defense attorney in your area.  If the parties are gearing up to get you you need to be prepared.  Good luck.
