I have a 2nd character I use for this sort of thing. His sole purpose is inconveniencing others.
The sort of sh*t he does is:
Sticky Bomb Apartments
Carobob drop a boat to block off LSC.
Play survivor, find where others camp, then sticky bomb it in between waves.
Carobob drop a boat to block off Apartments
Kill store owners, and camp in store waiting for player to rob.
Play golf and hit the ball out onto the road and deliberately get max score to waste time.
Change lobby settings at last minute to something sh*t like 99 laps of bicycles.
Camping on top of the Golf Club, murdering anybody who feels like a game of golf.
Blocking the entrance to LSC with ignition bomb rigged cars.
When somebody starts a gang attack, I go there and support the gang.
My crew emblem is a picture of giant dick.
Get a bounty put on my head, then go sit in my apartment all day.
Invite people to missions then leave, and wait for them to leave, then blow their face off with my shotty.
Sticky bomb planes at GSD Airport
Blow up Simeon wanted vehicles
Get to cargo drops first, and sticky bomb them.
Join team deathmatch, and hinder my own team mates by deliberately getting killed, and just following them and standing in their way, drop grenades at their feet, all that sh*t.
Quit on the 9th hole of golf, so they don't record the win.
Play a GTA Race and block the finish line with trucks.
Piss somebody off, get them to chase me, go right out to sea, when they get close, start a job from the start map.
Call mercenaries on people minding their own business
Park 37 cars in front of the impound gates, so players get shot trying to steal their cars back.
And lots of other sh*t, all for sh*ts and giggles!
Come at me Brahs!!!
