I've texted this number and I'm 99% sure it's some sort of scam. I have a strong suspicion that the "Lexi 403-612-8206" sign that's being held in the pics has been photoshopped in, as the sign just seems a bit too clean and in some of the pics it's just floating in mid air without being held, lol. Also, despite the ad saying that you can ask for pic verification, the second I asked for that during our text conversation they stopped replying. Also, it seems strange that the pics still don't have the verified Leolist check mark beside them despite being up for quite a while and having all the essential info on a sign.
Not sure exactly what's going on over there, but it's definitely shady.
