To whoever left several hateful, confusing comments on older posts in the last 24 hours: this behavior constitutes harassment and Cyberstalking.
“Cyberstalking is the use of the Internet or other electronic means to stalk or harass an individual, a group of individuals, or an organization. It may include false accusations, monitoring, making threats, identity theft, damage to data or equipment, the solicitation of minors for sex, or gathering information in order to harass. The definition of "harassment" must meet the criterion that a reasonable person, in possession of the same information, would regard it as sufficient to cause another reasonable person distress.” Wikipedia.
Don’t have time to deal with bizarre behavior now, leaving on vacation.
