Sounds like a really spammy and annoying way to promote an app. I assume someone else who has your phone number signed up on their app and gave access to all their contacts. Then the app sends out spam texts to get you to sign up.

Depending on where you are located, you might be able to report it. Otherwise just drop them a bad review, or name and shame them here

edit, I assume it's this: https://slickapp.co/

Yall, high-school yearbooks are public records.

What happens is some kid gets a gossip app which takes their contact data and then uses it to send this shit.

I used to get it pretty often too when I was in school.

This reminds me of the anonymous confession thing that made it's rounds on Facebook several years back. My cousin would post links to his every day with messages like, "Let's see what you've got" or "Give me your worst" attached to it. I suspect he was desperately fishing for compliments, or hoping for anonymous love confessions from the girls he was flirting with, as he would also post scrambled love letters on his wall that he must have figured these girls had time to sit down and eagerly unscramble (ie; I VELO UYO YLSHAE RMOE NTHA HTE UNS VELOS TEH ONOM). I always made sure to anonymously let him know what a stupid, annoying fuck he was being.

Those LinkedIn emails are getting out of hand.

Don't keep us in suspense! What did they say? /s

Google your name. There are a bunch of websites that will list your known addresses, affiliates(family or people you have lived with), phone numbers, social media, etc.

That data is collected through various means and then are sold to interested parties.

2010 Facebook is that you?

As a homeschooled kid, let them come.

They might not know know, but there sure can be a lot of meta data one can use to determine that a person goes to school, where it might be, and what school it most likely is.

Or someone else straight up posted the information publicly. That's always a possibility you have to consider.

Either way, isolating certain websites and services from each other and/or the rest is certainly a good practice to limit what they can gather about you. If you don't do that already, that is.

This is why it's good to be middle-aged. If anyone I know was described as my 'friend in _____ school' without naming them, I'd just assume it was someone I don't remember anyway.

Looks like a great way to phising
