Tacko Ink is an organization of people who terrorize others with extreme annoyance, spamming (and freezing) your computer through messengers, and flooding forums with nasty pictures, usually because they deserve it. Tacko Ink is a very feared organization. All fear the Tacko, regardless of whether they realize it or not. All fear, and all hail. Tacko Ink is short for Tacko Inkorporated.
