Facebook and Your Cell #

I just found out yesterday that you SHOULD NOT put your cell # on Facebook; like when you take the quizes. I did not really thinking about it after I took a quiz and I was charge on my cell bill for $20 for PREMIUM TEXT!!!! Sucks...

I have been getting random texts about random facts and did not really think about it. I have just been deleting them. What I was told yesterday was to reply to the text with STOP or CANCEL. Otherwise I will be charged montly for $20 for PREMIUM TEXTS. Just thought I would put that out there.
