Botting, never truly 24/7?

Depends. I have had a 3 day SorcGarden proggy, and after that it updated and logged, just managed to get a picture though. Sometimes, it closes automatically after about 12 hours, even less. It's all down to making sure that you can keep your computer updated fully when you are NOT botting, and if RuneScape or your bot updates/needs updating, that's just hard luck.
