It always pays to read the fine print whenever you share your contact info.Spammers Bought Your Information: Data-broker companies collect people's information and then resell it to other companies for marketing purposes. While this is very annoying, it's not necessarily nefarious. Lots of reputable companies sell customer data to brokers.
