Words with Friends: Game App? Or Dating App?

When did Words with Friends become a dating app? I used to play a long time ago and recently decided to start playing again.  A few days in I started getting messages from players with profile pictures of older men.  Each one tried to get me to tell them my location.  Every time I said I do not give out my location.  Some were persistent and asked why not.  Others just blocked me or resigned from the game.  One guy said "I hope you don't mind if we get to know each other better".  Another said "I am just a friend" when I said I don't give out my location to strangers.  I ended up changing my profile picture from a photo of my face to a photo of a caterpillar.  That seemed to deter the unwanted messages for awhile.  Yesterday a new person sent me an invitation for a game and I accepted.  Again, it was a picture of an older man.  He ended up sending a message asking for my location and when I refused to tell him he resigned from the game.  I have always been a little wary of giving out information to strangers (probably all of the true crime shows that I watch) but the sad thing is that there are people out there who are naïve.  There are people who probably don't know any better that will give out personal information.  I would like to know what the end game is here.  Identify theft? Trafficking? Or are these guys hoping that someone will "sext" with them? After the first person messaged me I kind of just laughed it off but then I was getting at least one message a day.  Anyone else have this problem with game apps?
