You being serious here? Your rep goes back to neutral. They won't attack you for all that long, maybe a couple weeks. And getting a slave is really easy, if you dont care who you enslave. I can go out of base, and generally in the first or second encounter there's an enslavable npc. Bag em and tag em.
Being a slaver tags you as hostile regardless of rep, same with all npc factions.
That is False. Unity and Rangers don't insta attack me anymore since rep went back to neutral.
If you want to make enemies, try to change something.
