SKULLs at Rosso Poker, what does it mean?

This skull symbol/graphic showed up next to my name a few days ago on Rosso Poker. (see image). Has anyone seen this before... Has someone put a hit out on me? I'm going to ask Rosso support about it but the last time I contacted them, no one got back to me for 2 weeks... That site is whack anyway... I wouldn't be depositing any money there... 1. too easy to win 2. way to easy to win money 3. very strange site and constantly having technical difficulties. The ones running out of someones garage always do. Hahahah
