Should business firms be allowed to call cell phones with advertising messages based on location?

No, I believe they have no right to invade someone's privacy in order to call their phone number just so they can make a buck or two and advertise their sell. There are my other creative ways to advertise that does not involve calling a stranger to buy a product; people can watch it on tv, listen to the radio etc. Individual need to understand that a stranger calling is a spam regardless if he is a sales business man as long as he is not on the contacts he is a spammer; phish of individuals personal en information and selling coupons from a abundant company domain that has been used so many times for spammers and even hackers. Therefore, an individual should always block outsider contact numbers that are doubtful. If an individual would like to receive phone numbers from business men than they can check websites of companies that safely and spam free for their customers in call line. Otherwise an advertising call is a no no toward all the factors that I have mentioned. Therefore, advertising call are unknown to individuals as they are not trustworthy and that an individual should block outsider advertising calls; out of sight out of mind hope this helps :)
