I got a text message from the exact same number: *******797. Message as follows: "Hi, I saw your lost pet ad. Wanted to let you know when I lost my dog I used StrayPost. Helped me get her back pretty quick. One sec, I can get you the link." [sic]
If I figure they got my number from one of the ads I posted up (I've posted physical posters and ads on facebook local lost pet groups). If anyone gets any more information on these people please let me know. I'm interested in seeking recourse.
