Why do people be mean on the forums?

There is a simple answer- they want attention! Or they are just showing off, which I really don't like. If there's a forum saying Only Furis, or I'm leaving Moshi!, ignore them! They are just putting up an untrue message, and they're also saying LOOK AT ME! So be real on the forums, and if you want some safe discussions to go on, look for ones by a moshi staff member, or a trustworthy monster.
