Who is behind this number??

Person sent me a text about my Craigslist posting for large dollar amount items, saying they want to purchase them and for me to send them my name and address for bank check.  I said cash only and they said they had no one to bring me cash! Said they would send their "movers" to pick up items once bank check clears.  Seems strange... wording on email appears to be spam.  Certainly not willing to give up my personal information!

Ever since I put an add in Craigslist I've gotten nothing but scam texts!.. This number 312-945-7961 text me also saying the same as all the rest, that they want what I'm selling and give them my name and address and they will send me a cashiers check for a large amount and I'm to take out the amount that is due to me for my item  and to take the rest and pay the shippers they send to pick up my item the balance!.. Wow what a very costly scam to the seller!.. I've gotten 4 different ones in the last 3 days and they all say the same thing!.. And they are all across the country from me!.. I wish they would bust these guys!

I also received scam texts from different numbers:

312-945-7961
858-848-7885
323-425-9049

They said : tanks i am ok with price i will be more than happy if you can help me mail it to my son as birthday gift were he study zoology in overseas i will offering a an extra $100 for shipment. I am paying now and upfont via paypal. Give me your paypal email address....

I looked this unknown number up and it said it was a scam number and there trying to offer me more for it and asking for my info didn't give it.
