I got put off joining any Roleplay that wants an Rp Sample, I understand why some people do it, but it's stupid and annoying when they get all silly about it like what happened to me.
And I agree about the whole 'stealing members thing' if someone left you for another then it's either they are bored with the current group and\or simply find the new one more interesting, or you did something to drive them away. simple as that.
