TBC doesn’t eliminate bots.
Perhaps you forgot about the subterranean herb and mineral bots that no kidding some how existed under the map and could loot from under the world?
Maybe you forgot about the warlock and hunter bots that farmed elementals endlessly 24-7?
I didn’t, and ya know how those were eliminated? Permanent bans, because blizzard actually cared about is in TBC and vanilla.
