Warning for "Grief" Tactics?!

[Denji]

Again, I do not even know if this was what I got an infraction for. I do also leave people dead on the floor often.

That's not the point. If you feel this is in error then you have an option to challenge it and should. I am not saying you have or have not done this, nor am I attempting to place blame. Not telling you what rule was broken is pretty standard procedure because you can use it to retaliate against the person (or in this case, people) who filed it.

You can still play. You're not banned. Challenge the decision and prove them wrong by being the decent player you know you're capable of being.
