1) OSBot is active, but people here will be biased of course.
2) Most boring skills (agil, RC, hunter) etc have highest ban rates and obviously the more click intensive = higher ban rate I guess/
3) Jagex can chainban accounts if their not on a proxy - and if you use a main account to mule you may risk a RWT ban however they are fairly unlikely unless your transferring enough to get on Jagex's radar (300m+)
4) F2P has a higher ban rate - some even hourly. P2P can last long on weekends I hear.
5) Don't talk about other botting sites here or they get aggy.
