so lets, hypothetical say youre a serial killer, and hate a certain community or a certain someone, for example lets say your ex, rather than hunting down and killing the people behind the community or your ex create a huge path to blame them for the deaths, in multiple ways starting off with:

faking getting blackmailed:

if you get caught make sure after every killing you create a fake gmail act like your ex or the community such as "kill this person or i will leak everything you ever sent to me"therefore putting you as the victim and like add a attachment a video of you pleasing yourself as a "teaser" this will lead the cops or decatives to think you were controlled to kill certain people, and dont forget to add information about the people youre killing so the cops actually believe it, putting in the loss of everything but getting your ex charged with it instead.

planting fake evidence:

one thing i like to do is get dna samples from the people i hate like hair and finger prints, after each killing you put the exact finger prints and hair strands perfectly to match your hater, by that you would be able to trick the cops into thinkin your fake evidence is actual ones.

killing people your haters hate:

For example your ex hates a certain group of people and she is known to hate them, you would therefore grab samples of her dna most likely hair and some blood with some finger prints, kill each single person by adding a small amount of evidence, since you probably dont hate thoe people you will be off the radars therefore making the cops suspect your ex

:destroying a random community

this is the worst of them all a straight dickhead move, record urself killing ur vicitiims but BUT make sure to like mention the community and say its for their sake for example, "THIS IS FOR STEAL A BRAIN ROT anything for a strawberry elephant" each time you kill, when they find out and intergate you remmeber to say you were influeced by that certain community to commit those acts
