Evocator, provocateur (from Latin evoco - “I call, to be called”) is a person who provokes, stimulates people or public opinion in society. As a rule, crudely provocative methods of provocation are used, which can lead to conflicts, and sometimes to serious negative consequences, both for the current provocateur and for the people around him, as well as society as a whole.
Evocators are capable of deliberately creating provocative people (according to the idea of the provocateur), who spread hostility towards other people through a hostile interpretation of facts published on the Internet. You don’t have to look far for examples - just remember the meme “do you want to lose weight? Go on a diet!”, published by the widely known social network VKontakte.
