Just curious, I got this text right after I posted a for sale listing on craigslist with my number on it. Anyone else using craigslist when they received this text?

who does this number belong to?

I received this unwanted text as well.  Report the number to your carrier. I did and they told me to reply with the words STOP in all capitals.  If you get an unwanted text from that number again inform your carrier again and they will take further action.

I did receive the same text about some on-line dating site..?

Same here
