Age limit allowed to play game

We have been attacked by player who claims to be 8 yrs old. This has been confirmed by others. He is now using fws to keep others from attacking him. Is there an age limit to this game?

There is another thread that answers your question.  Thread is "How do you verify age?"

If they really are 8 years old, they lied to get into your game. Guess you need to add a disclaimer to say if you lied then don't cry if your destroyed. "There is no crying in Jotun" 

I cried a lot when I first got here by being attacked by Frobort (or Frobot or whatever his name was) he cured me of my tears.  

Usually by COPPA standards, most social media sites/MMOs claim 13/14 or up. I'd say that anyone can play this game, given that it isn't that violent for most people. I know dozens of people who claim that they spent their childhood online on sites like Big Fish Games, flash games, and MMOs like Grand Chase and MapleStory.
