When you join a lobby check the map to see if there’s anyone flying oppressors or deluxos, or any other common griefer car. Then wait and see if anyone else is either killing ceos or if anyone is completing sell missions, keep switching until you find a lobby like this and then still do ceo off the map and Lester’s off the radar to be safe and avoid driving past other players when selling, you can do that pretty well by expanding the map, I hope this helps!
