Yeah.. i noticed quite a few (3) disconnects the other day when having DB open. Then.. low and behold, tripwire was hit the following morning.
Just from experience, when I was botting on wow, I would get disconnected roughly 2-3 times in 8 hours. Then surely enough, I was banned for 6 months for 'exploiting the economy' which we all know is their ban warning for botting. In conclusion, I'm pretty sure getting disconnected randomly and often means they are onto you for botting, essentially you are already fucked and eventually will get banned.
Before I started using DB, I would sit and play for 12 hour sessions and not disconnect once. Now, I disconnect 2-3 times a day. Will I be banned from diablo 3? Probably.. was it worth skipping all that farming? Definitely. Risk vs. Reward.
