Give them your ACTUAL phone number? Wow, that's like putting ur real name on the internets, not a good idea.
why the hell would you give a website your number?!
Yeah, it was not exactly my smartest moment, considering I have safeguards on my other accounts and information. I thought it was strictly used to prevent people from cheating the system with multiple accounts. According to their "Terms of Use" and "Privacy Policy" they don't give out information, and I didn't see any clause about any "partners" contacting me.
Vegeta, I think you had the right idea about partially posting information. Next time if they don't specify the "need to know" information, I'll experiment with as little information as possible.
Thankfully, I found a way to delete the number from the system, and confirmed that I erased it.
