Don't respond to them.
I just went through it.
They text you so you contact them by email and then they have your email address.
If you let these craigslist losers contact you by email you'll see at the bottom of each email, craigslist puts a link there that you can click to report these scammers.
If you text back and forth you can't report them.
Just text back that you know they are scammers and you are reporting them - the texts will stop.
Thats what I did.
got a text from this number refering to an add on craigslist. a marine biologist that wants to buy my car for his brother. asked me to create a pay pall account.
