Does your Ning site have rules?
I had to suspend a member for the first time a few days ago. She would break the same rule non-stop. She wouldn't stop harassing another member that happened to be my sister, i gave the girl a warning and she continued, so the day after i banned her i noticed i had a new member and the name sounded a lot like something she would use, so i thought has she returned just with a different email? Now, i don't what i should do about this new member.
