I received the following text message from this number:
Are you short on funds? Get funds transferred to your account today. Text YES to be contacted. Text NO to be removed from the survey.
Got this as well. I've been trying to track down who it is to find out who sold my number out :/ Grrr.
I'm hesitant to text back the number as well to have them "remove" me from the list, as I fear that that's usually just indication that the number is alive and thus your number gets resold to the next bidder.
