Who called from 9712950602

This number texted me stating  " i posted pictures at hottpics.com. By the way this is Mary".

I just posted pics at. Www.superhot.com by the way this is mary

I just got a text from this number and this nasty message..this is my work phone and so isn't a published number. Hi i just put some pic on www.superhott.com it's Mary by the way. I do not know a Mary and do not cruise those types of sites.

I received the same message as others.  Mary from superhott.com posted pix.  This is extremely unwanted and unnecessary

Same message ... how do I get my number off of this list?  How did they even get my number?
