A Ruiner is a person who habitually exhibits a desire to spoil or ruin things, often focused on a particular theme. Different from a [hater] in that a ruiner tends to hold deep, genuine, and long-lasting animosity toward their target which can reach obsessive and psychologically unsound levels. Ruiners have a tendency to latch on to specific people, whether they are famous or not, and perform stalking-like behavior. Ruiners who are members of a subculture such as a fandom, may paradoxially focus their hatred on their own topic of interest and attempt to throw wrenches in it or spoil the enjoyment for other people.
