If you see any kind of drama going down anywhere on the Internet, it's usually best to not get involved in it because doing so could be something you could regret for the rest of your days. For example, if you see someone you know and/or love getting beaten up in an argument, don't try to intervene because you could give people the impression that you're a white-knight. Who knows? The person you know could have decided not to reply because they may have thought it was better to not keep the heat going. A lot of the time, it's not worth it because it could do some damage to your reputation.
