Same in Fallout 76 which is a cooperative PvE casual game, enjoyed by the fabled middle-American casual gamer Mom. (And Dads, and anyone else who isn't playing for competition.)
For some reason, some players spend 3 figures at RMT sites for weapons that can few-shot the server-wide event bosses. There's no in-game benefit for this. The boss events are designed to entertain a half dozen to dozen players for 5 - 15 minutes. Insta death for the boss just means everyone has to wait longer for the next event.
Other players use a glitch in the game that lets them blanket the event zone with white explosions, so no players (including themselves) can see the event. The only recourse is to switch servers or just leave the event.
This phenomenon is interesting enough to have been researched:
"Results support the relationship between self-determination theory need satisfaction and enjoyment, and indicate that griefers enjoy their gameplay style as much as community-based players, despite the antisocial nature of the gameplay style resulting in differing levels of need satisfaction."
