If I would bot I'd do so past 10PM GMT+1 to untill 6AM on weekdays, weekends are safer however preferrably same time schedule. This is to avoid manual bans. However, this new jm*d, i think, bans at his home. Be careful.
Why the time? Try avoiding JM*ds regular working schedule.
It's slightly more freely to bot on holidays however try sticking to the time schedule stated.
