2) In a day... I usually bot 1-2 hours depending on what I'm botting for.
3) In a week... I bot about 10 hours total.
4) I've been botting since '11
5) That just depends on what you are trying to bot for... If you are trying to bot for Legion Tokens, I'd prefer a private room. Whereas if you are trying to bot Mana Golem, I'd prefer public areas.
Hope I helped!!!
