Nice name man.
OT: Smart botting, act like a human. No more than 16 hours a day (though some people can bot 24/7 without bans). Make sure you take your breaks manually too.
Depends how much you care about the account also, atm I'm suiciding an account from the ground up until it gets decent stats
I managed to do SoulWars, Agility, Thieving, Hunter all at 12 hours a day and I am still not banned it depends on the bot I guess, but 12 hours is about the most a human could do of Soul Wars a day before wanting to go stick a sharp knife through their neck.
I'd say 4-20 depending on the quality of the antiban and such. But bots like hunter, alch and sudoku, 4-6 hours only, since they have the highest ban rate
i don't see the point of "safe" botting, no botting is safe, just go for the gold and suicide 20 hrs a day for a month than stop botting for 3 to 5 days. also u will not get banned in places people can't see you, jagex's bot detection system is player reports...
Theres no such thing a smart botting, the longer you bot the more chance you have of being reported.
If you want to try and mimic your normal playing time, then smart botting would be that. If you play 8hrs a day, then 8hrs a day. If you play 1hr a day, then 1hr a day.
