This is because on the internet, we really never know who another player is, where they are, or what their intentions are.  The absolutely safest measure you can take online is to just be anonymous.  Players on this game are of all ages.  We have grandparents and 7 year-olds, and we have no way of differentiating between them.  So this rule must apply to all players equally.  Horse Isle is NOT a website for meeting real people.  Do plan to make friends! But they should remain online, in-game friends only.
