Early am (1:53a) text from unknown person "Natalie F" stating "I wanna take out your peenccil and stick it in my pencil case". Then writes "text back"   Would you be able to determine who sent this?

These are different girls using this number to text & harass people sending porn links.  I've done everything I can to scare them off, promising to even give their info to Homeland Security, gangs, the klan, you name it, nothing stops the little snots.

Forward the texts to 7726 - your telecom provider should block these for you.  Or you can download one of the free apps which block spam calls and texts.
