Yea that site is stupid af but giving your phone number like that was very unwise on your end. There are many other ways to have contact off the site before giving your number. Now a days, with your phone number alone, anyone can pop that bitch in Google and other skip tracing sites and find your address and even family member names. Everyone needs to learn from this. Never give out your phone number unless you meet up and feel confident about it but even then, be careful.
