What's the worst place you can give your number out to?

I was recently trying to find my mother some insurance. In the process, I submitted my phone number online. Now, my phone constantly blows up. What are the worst places to give your phone number out to so I can avoid making the same mistake in the future?
Okay this is actually about my mom's douche ex bf. He's blackmailing her and this is one of the many ways I plan to get him back. I know this is kinda lame, but those anoying 3am phone calls really get under your skin. Especially when he'll be charged for EVERY SINGLE ONE OF THEM. :)

His numbers (in case anyone has an interest in helping) are:

918.264.2476
405.761.5184
