Trolls

Most troll users contribute almost nothing to the site except to cause anger and confusion. There are multiple trolls:
*Benign trolls, who don't do much but add a heart or a mustache or hat or some silly character constantly touching your art.
**Examples: Penus, Trypsonite
*Trolls, who otherwise draw and write normal (compared to the trolls below) but will sometimes lash out and scribble over your artwork if they find something they don't like. Generally annoying people.
**Examples: LiyaDaGreat, TERKO
*Rare trolls, who are actually creative about their trolling. They are extinct these days.
**Examples: noooooooooooooooooooooooooooooooooooooooone. It's sad.
*Hackers, who, if angered, will hack and even crash DoodleToo with giant pens and sprays.. Avoid at all costs.
**Examples: Nax134, Trypsonite, EcksDee
