They responded to my craigslist ad via text message. Tried to set up a tutor session for their son, but they wanted to get my home address (uh, no) so they could calculate gas or taxi for me :/ English is poor.

The number is definitely held by a Nigerian scamster. responded to a want listing I placed, but English poor and shows all the flags. I.P traced to Lagos.
Report this person if they contact you.

"Do you still care for a job and do you know how to post ads on site like Craigslist?"  This sender sounds foreign! They can't even put together an English sentence decently.
