Well nothing is SAFE I guess. And yeah it is detectable. If blizz decides to launch some kickass warden update that fools ISXWarden and detects IS and OB you will get banned, and If some GM decides to check you out he'll probably notice you botting and ban you too.
HOWEVER, as far is botting is concerned this is one of the safest ones around IMO, if you have it set up correctly. Sometimes it does some stupid stuff that other players might find awckward. But it still acts fairly natural. I've been using it for a couple of weeks now and I'm still around. In fact, after I finish typing this I'm going to turn it on and go to bed, since it's AV weekend
I would never use it on my main though. But that's personal. I reckon lots of players do![]()
