Is there something I can do about this?

[Gordanfreman]

I'm submitting a ticket to report a player Who's dual boxxing/powerleveling an alt. In the process sheeping my targets to botch my pulls so he can either get me killed or take the pull. Hyz is the lvl 60 mage causing the issues. His alt is Ppuubb a 42 warrior.

It really depends on whether or not they are actually breaking the rules. It is LEGAL to power level so long as two different players are playing. You cannot "Boost" yourself. If you just see them auto-following and killing mobs, this could also just be the person being afk temporarily. However, if they are just auto-following for very long periods of time, this is probably the same player playing two different characters.

Your best bet is to just screenshot/record them over a period of time, then submit your findings to a GM. They will look into it to determine if they are breaking the rules.

But there is nothing against Grieving in this manner?

Worst thing you can do is keep feeding the troll 'cause he'll just keep coming back for more.

Either quest somewhere else, logout and come back later, or - my personal favourite - leave your toon in-game while you make something to eat, leaving him stood around with his thumb up his ass.
