Commercial use of info: Is the commercial use of personal information ethical?
More targeted advertising is of greater value to the consumer. Why should we complain that advertisers will have more information about us to advertise to us things that we are more interested in buying? Advertising is not evil. Ads inform the consumer of a product that they may judge to be of value in their lives and worth spending money on. No product is being forced on consumers by ads, but offered as something that the consumer might deem worthy to purchase. Therefore, it should be welcome that social networking sites offer advertising firms information that can bring products of greater potential value to a particular consumer's attention.
It is unethical for social network sites to use personal information to enable advertisers to better target you as a consumer. Personal information should not be used to allow companies to attempt to sell you something.
