Would it be better to bot for a short time and take short breaks, or bot for a long time(8-12hrs) and take long breaks?

both are good there will always be a chance on getting banned even if botting for 10 minutes and 23:50 minute break 

Agreed^. Just bot as a normal person would, I "BotWatch" Im usually in the vicinity of my bot to check up on it.

Think about it like this, if you're going to bot for 8-12 hours straight, add atleast a 1-2 hour break for taking into account normal rs breaks. Never bot 36+ hours straight even with occasional 1-2 hour breaks. Take a long (atleast 5-6 hour break for "sleep") break.

 

Or just bot when you wake up until you go to sleep then shut it off ;)
