First on my list would be, just as an experiment, someone completely random I find online just to see what happens. You know, something that would somehow end up making major news, news big enough that I'd hopefully see it when my dad watches the nightly news. Just to see that the page works. My parents would never find the page since they don't go through my stuff, so I'd be safe there. Just gotta make sure nobody sees it through a camera, so phone and laptop out of the way when I write. Definitely burn it after it's all used up and everyone on it is dead to ensure nobody sees it. Wouldn't be that hard for me to put it in my pyrex bowl and light it up.
After confirming it works, get to work on some of the people I wanna see gone for whatever reason. If a torn/cut off piece works, you bet I'd take some lines and cut them before cutting those into smaller pieces. Then store them in my wallet for any time I'm out and about and have a surprise Mormon missionary pop up on me. Sounds cruel, but I ain't got time for them and don't know how to effectively tell them no. Just have to have them sign the slips, with me asking for an autograph or something before I leave.
The rest would go to various people. I think some of my biggest targets would be looking up the mega pastors here in America and having them reveal to all their followers that they have been scammed the whole time, calling them the dumbest sheeple on the planet before ending themselves somehow. Mega pastors deserve it for stealing money from the gullible.
Next would be a large group of CEOs from large tech firms. They'd probably have enough time to clear their schedules and meet up with each other, so there would be a livestreamed MMA match to the death, after telling the world how they've defrauded everyone and that the class war is on because after the match they're sending kill squads to eradicate the poor. So probably have them use their wealth to try and coordinate that as well and set it up so it doesn't actually happen, but that they planned on making it happen, with verifiable messaging/email to prove it. Really set the world up for chaos, I guess. Winner of the match would just kill themselves, I guess, IDK what they would do if anything. CEOs like the gøøg|e, amazøn, twatter, fakebook, redd¡t, and maybe a few others sound good to me because they definitely screw over loads of people.
I think my 3rd set would just be a single target if I could figure out who they are. Just gotta figure out who the head of the American branch of scientology is so I could make that fool reveal all the crimes he is able to reveal that the wackjob cult has ever committed here in America by making sure they're all made publicly available by making the records public domain and widely available while also making him get rid of their tax exempt status by having people lobbying the government to permanently remove it forever to add insult to injury. Let the people know what that cult is all about while simultaneously ruining them.
Though, after that, cannot think of any other local (country wide) targets, so from there, probably go after some big names I cannot say because I don't feel comfortable saying. Politicians and dictators are a scary thing to have hunting you over the fact you make a post about wanting them gone, so I'mma end it there.
Don't know how possible some of this would be, but you gotta admit it would bring chaos to our world and really shake up the status quo having all these things happen.
