I had one number for like 5 years and had no problems with this crap. So after throwing the old one deep in the bin due to some bitch pestering me I got this one a few months ago. I have probably given the number out a cpl times to some IM sites cos they force you to for some singup shit (I really hate doing it). Now I am getting stupid offers and have no idea where they are coming from. I just checked the message and it;s form these fuckers: http://smscaster.com/ so definitely some IM shit. How do I stop this? They gave me an opt out option in the last one which I replied to and apparently it was bogus. So how do I stop this crap?
