Fake accounts ?

I’m new to this app but in the few weeks I’ve been using it I’ve fallen in love it’s such a great community. However ladies there is a disturbing number of fake accounts on here . I’m not sure if y’all have noticed. People claim to be 11 weeks with a single baby they 7 week with twins a week later in there next post. I’ve seen pictures shared of people and their bump. Except it’s a phot from an add. Why in the world would people do this ? Be really careful about what information your sharing on here. Her world can be a really dangerous place.
