I received a TXT with HAHA my name and something that would make you think you were receiving a link from facebook. Also received a txt from 503 267 0812 similar txt.
The thought is this is coming from facebook and that you would need to change your privacy so that only your friends can look you up by your phone number or email.
I have Verizon and have been getting the random phone calls from numbers and I block them but you can't block txt messages!
