Last week someone texted my wife saying that they had information about me cheating on her with escorts. I convinced her that it was a scam due to the amount of information publicly available about me.  Is this happening to anyone else?  A search of the phone number doesn’t reveal anything.

END OF MESSAGE

But in this case, it's from a rather stupid scammer.  Usually, they would text you first threatening to text your wife UNLESS you pay.  

 
Texting her first blows the deal.  

 
But consider some alternates, like someone from your current or past who doesn't like you. Or someone from your wife's current or past who DOES like her and is willing to try to (anonymously) destroy your marriage to get a chance with her.  

 
Save the screen shots, document the text details (number, time, etc.) and if you are contacted again, file a report with your local vice/fraud desk at a police station, or FBI.  Whether you see escorts or not, extortion threats are a felony.  

 
Life is good

Did they ask anything from her in return? Unless they’re trying to get something out of it, it’s not a scam, or it’s an idiot who doesn’t know how to scam. The fact this person went directly to her sounds more like someone who has it out for you.

As mentioned some scam/blackmail attempt is not going to contact your wife first, largely makes asking for money to stay silent a completely moot point. Seems like it might be an odd way to go but maybe they think your wife would be more ashamed if news of the cheating were to become known so might pay to keep it quite. I would not expect that approach though.

 
Sounds more like someone knows something about you and knows your wife too, and perhaps is more a friend of your wife than you or has some moral position they have to live up to and not saying something would bother them. Given this is causing you a problem, even if you dodged the bullet this time, you probably should rethink how you are doing things if someone can find out that much about you and your relationships.
