My concern was the "bad advisors", whatever you mean exactly. Giving false advises? Giving not very detailed, or too detailed and spoiling advices?
I see. In general, those that break
the advising policy. Like I said, I've seen people powerlevel advisormode in the past, in hopes that when they hit 500 advisor points they can fly around like a GM (again, advisor points are hidden now). I've also seen the spoiler kind, and the kind who use advisormode for finding guild recruits and platinum miners. Any more I just use advisormode to entertain myself.
Also, since 0.3.020, most of the questions I've seen come up are tutorial-related. Out of the rest of the questions, about half of them ask for spoilers while the other half of them require GM intervention (where petition is more appropriate).
