Actually no they don't suspend people. I have reported one player for griefing (the same thing as the OP). This is what I get from the report.


The person basically did nothing but talk in chat for 20-30 minutes. They finally started to do something after our second DPS came in. We didn't want to leave because we thought it would be rude for the DPS because they have to wait 30+ minutes again. We never even finished it up because they kept fooling around, dying (purposely standing in the stuff) and blaming me for not healing them when they pulled more mobs and I was mainly healing the tank so we wouldn't wipe.
