Depends on what you did, for example a account 6 years old with no problems or prior bans or warnings. someone reports you for botting and a GM finds you botting. This will more then likely resort in a 3 day ban.
Brand new account, 100 quests done, mining and herbing maxed and your botting. More then likely a perminent ban right away.
Regardless if your picked off it can be a perma, so don;t bot if you care about losing your account
