I'm sick of bored, malicious, immature (take your pick) players using the new nudge feature in DTV to either shove someone (fellow player) off a high cliff or roof to their death because of the height. I've also I've seen players nudge others off roofs into a number of pooled enemies to certain death.
There needs to be a way to report this behaviour for kick or ban purposes.
The problem with the nudge feature is it usually happens from behind, so you don't see the player that pushed you, and there's no ability to report for any injury suffered. The best workaround I can think of is a log entry when someone nudges you - "player x nudged player y". Coupled with some kind of screenshot of you landing in either a pile of of enemies or seriously blackbarred.
