Invisible randoms?
Okay, let us start from square one. Invisible randoms as you call it, are most probably JMods snooping around.
Botting always brings a risk of being banned. No matter how good your anti detection methods are, if you bot in obvious places, your bot will not behave as a human, resulting in being reported or JMod bans.
For OSBot 2 we have studied severals thesis about bot detection. We have taken these serious, as it's very likely one or more of these methods are used. I'm currently experimenting with one of them in OSBot 1, which will be in OSBot 2 along with some other very serious pattern breaking features.
I have a very high level account, which has been botting many hours but in a normal way. Bot smart. People get banned everyday, especially if you're in the goldfarming market. Create new techniques to avoid bans, build your accounts a little before botting in more extreme ways.
