Unfortunately there is not anything we can do about players who act innapropriately in the game. It is not our realm to moderate.

However, oQueue allows you to reduce your chances of finding yourself with that person again. I would suggest awarding that person negative karma, by right clicking their name in oQueue, or using the log book on the upper left, and find their name. Then use the down arrow to award them negative karma.

Also I would suggest adding them to your oQueue ban list so you do not see their groups anymore, and they will not be able to see your groups.

"adding them to your oQueue ban list so you do not see their groups anymore, and they will not be able to see your groups."
but both of you might join somebody elses group
