Some dude wishing death upon my family and child after canceling a duel

Hello,

There I was chilling in durotar and some random dude with a paladin duels me, and when i canceled the duel since i was busy watching over my kid. I explained to him that i cant atm and why, he started wishing death upon my family I hope thats enough of a reason to send the guy on a small vacation from this game cuz obviously he is not equiped mentaly to handle it.

Block them and move on.

Right-click player name -> Ignore Player, no? People running their mouth isn't a bannable offense, unless otherwise specified in the rules. Speaking of mentally equipped...
