This account I've just being banned 5 days ago because of leveling by herb and mining from 80-85 and played again 2 days ago .I leveling 85-86 hand by hand in 2 days, each day about 10hours but blizzard closured my account too .What must i do now?
Leveling your character by just strictly farming is very "bot-like" behavior, whether done by hand or not. But as Thatguy93 said, just appeal it and say pretty much what you said above without mentioning anything about 'not being a bot' etc. A call to Customer Service might help your case too - they can't unban your account, but they sometimes put notes on your account that the GM handling your ticket will see which can only help.
Appeal it, I've been unbanned twice in the last 2 weeks for gathering, sounds like their auto-systems are screwed up atm
When was the last time you botted? This could be a delayed ban from that. Just because you were banned while manually leveling stuff doesnt mean a bunch ofpeople didnt report you and it just took longer for a GM to investigate you.
