Jagex dont have the resources to specifically monitor certain accounts, Idk what these guys are talking about
You got a 2 day most likely because you weren't using a script that pumps money into the game, I dont personally have any experience with the 2 day bans but I always bot combat only and have never recieved a ban doing so for 3-5 hours a day, you doing 8-12 is too much imo
