If a man walked into a brothel and claimed afterwards he was just looking, would you believe him? Yeah. People who make these threads and ask about the "limits" of hacking are only asking because it concerns them personally because they do it, or are thinking about doing it. If someone was legitimate they wouldn't give a shit about what can and cannot be detected in hacks, as they themselves are not cheating. It's common sense.
Bottom line, if you don't want to get caught cheating, don't do it. And I'm surprised these garbage threads stay open, they ruin stark mountain with their presence on a daily basis.
