I might as well ask here too.  Can anyone tell me why or how giving away my cell phone number on wall of coins is safe?  Do other people get it? what is their policy?  I have never ever given out my cell phone number to anyone but family and have enjoyed a harassment free / no sales calls existence with it.  So I'm pretty paranoid to give it out. Our home number on the other hand is unusable, I'm not sure why we still have it.  We never answer it unless we recognize the caller or are expecting a call.  So I need to know that this info is super safe. Any insight is very much appreciated
