This is our son's 9th call from them.  We don't know them.  We're in Nevada.  We looked this number up, and it's a cell number from Delaware.  It's the middle of nowhere.  We don't know anyone from there - neither does our son.  They probably don't have anything better to do.  However, this time, a man's voice left him disgusting, overtly sexual remarks.  We will NOT tolerate some warped loser/s leaving disgusting messages for our 10 year old!!  We have reported this sexual predator/s and their number to the FBI!!
