A couple years of one on one games was good, no problems there. Then I discovered the multiplayer games with four players per game. Bully central. Every game had verbal abuse of some kind. The site should have an age restriction.
I reported two incidents of bullying and harsh language, but heard nothing about their response. After the second reporting, all my chat functions were shut down. I could no longer see what players were typing. That was their solution I guess: silence the ones who report abuse.
About as good as any other place. Just don't let your kids near it.
