Anneurism IV might scratch that itch! Griefing isn't a bannable offense, though there are game mechanics that punish it a bit. Quite a quirky and fun game.
Rust also springs to mind, you can really annoy people using a lot of the in-game mechanics.
DayZ too with a bit of social engineering.
I know few people who absolutely raped the invite beta to the point where the discord of the game was nothing but complaining about them.
Helldivers 2. You can hoover all the samples and suicide into a vent, preventing their recovery, and everything you use to kill baddies can be used to kill your squadmates. The worst that can happen is you get kicked. Or at least that's how it was back about a year ago when I stopped playing.
When you play on super helldive level nobody cares about samples.
Ive played the game quite a bit and ive only come across one genuine retard, i could tell by his accent he was retarded.
Personally, l4d2 is an extremely easy game to grief.
Its simple, expert difficulty, have "vote to return to lobby" bound on mouse3. Initiate the vote and start killing the other survivors.
That vote will prevent anyone from votekicking you for its duration, and quite often people press f1 without reading when youre griefing because they think the vote is to kick YOU.
Just leave the match before a votekick can get called on you.
Change name, profile picture, repeat.
My highest streak fucking the same lobby with the same 3 people in the lobby is 7.
When ive done it, biggest obstacle to doing it is OTHER PEOPLE DOING THE SAME EXACT THING!
Its fucking ridiculous how many people are doing the same thing.
Oh and garrys mod, atleast it used to be, havent played since 2020.
Crashing RP servers with sweaty basers was always so fun to watch.
"oh you spent last 10 hours sitting in this base printing money and it took you that time to get this many printers? well fuck im sorry, i just accidentally spawned bunch of gear props ontop of each other with the fading door tool, so i guess youre gonna have to retry"
I remember once googling some annoying retards username which led to his facebook with his address, so we made a "retard kindergarten" base with a sign above it that contained his homes address.
We got banned half a hour later but not before spending that 30 minutes listening to some retard scream about how "THEY HACKED MY COMPUTER BAN THEM!"
Rejoined later when he was on with an alt, his name and real picture and i kept going from person to person telling them my home address(his) while calling myself a power bottom gay prostitute.
Good times.
Warframe letting you shit out infinite particle effects into peoples faces, teleport them around, yank them around, shoot out the windows and activate the air lock, etc.
Any game with friendly fire.
Years ago when some maps had "radiation clouds" you could jump through the cloud and you could deal friendly damage for 5 seconds.
That lasted a whole week.
