You ahve to make multiple accounts and keep on rotation between them. 8 accounts with 3 hours on each is very good!
The absolute max depends on what you are using.
SCAR/SRL = 8 (Best chance of not getting banned)
RSBot = 14 (Only once a month)
iBot = 10 (Unlimited if you use VERY long breaks)
well, botting on any account is catchable even if you just start. but, a safe is 5 hours a day, and jagex waits to use the banhammer on you when you most earn alot of stuff boting so bcareful dont let the banhammer get you!
Dont do one skill over and over again, Do some other skills every once in a while.
Turn "User Input" on once in a while, Talk to the people around you and do normal stuff.
Keep some quests done on all of your accounts.
Every once in a while report a player. JaGeX probably separates accounts into two category's, The ones that do simple things once i na while, and the ones that don't.
