Not sure if this should be here or in off topic, but there is an app sending text messages to people saying you have received an anonymous compliment, which after doing research is from a user of the app who has you in their contacts. You can stop getting texts from by replying "No", but still, I don't like how other people can give my phone number away without my consent. I get that the other person consented to giving them my number, but that isn't asking me.
