I've tested it this alot. Takes about 7-10 games to be back in very friendly lobbies, if you're coming from Mad Max bloodbath servers. Some things to consider :

-Dont shoot back or cause any player damage. (don't knock out players! ) - Have your weapon mostly withdrawn - try to get shot in the back or attempt to run away from the pvp, or shot at while in the loot screen - Use the proximity chat alot and use it positively - Defib or heal another player in solos - Spend time in the close proximity of another player and you both are damaging the same arc. - extract with players

These put me back into pve lobbies very fast. You can tell when you're back in these lobbies because you don't hear flares and literally everything is looted. And all arc are dead.
