After the incident Zatz decided to change his gamertag and requested Microsoft waive its required cost to change an online identity. Not only did Microsoft deny his request but Zatz claims the support agent was very "dismissive" of the situation in general. "Death threats must come in regularly, because the support staff didn't seem concerned." Eventually, Zatz paid to change his gamertag.
Should Microsoft be more vigilant about specific chatter on Xbox Live? Maybe, but with nothing in place to prove what's said it would be next to impossible -- it's your word against another person. We'd suggest players not egg each other along and then be surprised when someone takes things too far, utilize the reporting system on Xbox Live and play with the people you know.
