the.com/provocateur

means Someone who deliberately stirs up trouble or controversy to provoke a reaction, often with a hidden agenda.

from From French provocateur, 'one who provokes,' rooted in Latin provocare — 'to call forth' (pro- 'forth' + vocare 'to call'). The term gained its sinister edge through agent provocateur, the phrase for a spy or infiltrator planted to incite others into revealing themselves or breaking the law, a tactic associated with 19th-century policing and espionage. The English word kept that whiff of manufactured chaos even as it spread beyond politics into art, media, and dinner parties.
