Has there been a deflation of the word "gaslighting" recently? I used to understand it as "making person X or others believe person X is crazy (in order to discredit them)" but I see it used much more widely nowadays and I don't really see what it has to do with the scenario in question.
Setting different standards for themselves, setting other people up, even boasting of sabotaging others openly, surrounded by gullible and oblivious people, limiting number of marks, snide remarks, running in packs and claiming all authority while victimizing themselves. Gaslighting is rare but part of the toolset.
It lost it's subtle manipulation element too. Gas lighting was causing doubt to spread, using manipulation tools the abuser thought were flying under the radar of the victim. The victim fell oblivious to the changes in worldview. It lost all connection to psychotherapy when it became a politicized term.
