So wanted to ask about what to do in this case. Today within a short time on Ch 12 I came across 3 spots that looked like monsters had been grouped into a small spot where they don't normally spawn. In this case should one just leave it alone, can we safely kill them (Then Id worry someone see me and think I did it) or should we contact a GM in some way about this?
Try typing ~mapowner to see if an IGN comes up, especially if they've been mapowner for a long time. If you find an associated IGN with the situation, submit a report and a staff member can look into cheatlogs to see if that IGN had been flagged by the hack alert system around that time. You can safely kill the mobs though, don't worry! You will only be banned if you use illegal programs yourself or you actively benefit from someone using illegal programs, like being in their party, ksing them repeatedly (like killing the mobs they keep vacuum hacking when they're actually vaccing them), or looting their drops. So just finding weird mobs somewhere and killing them for fun is no problem, go ahead.
