Simple they are farming phone numbers. I have text one or two of these in the past on the old burner phone and never got a reply. Then a few days later I get hammered with unknown numbers texting me wanting me to join some damn site so I can see more pics or get "verified".

Read the text in the ad and you will see a website to join so you can interact with this particular one.
I forgot to add have you ever noticed how bad the context of the ad is composed?
