This has absolutely nothing to do with text messaging. Now, if for some reason you do find yourself receiving unwanted text messages, you can file a complaint. But, knowing the permission-based nature of this marketing method, you may never confront this issue.

The campaign rewarded customers for sharing the text offers with their friends. By encouraging sharing and word-of-mouth in their promotion, they leveraged their spending on their SMS campaign and managed to provide sufficient incentive that 17% of those who received texts forwarded them and 7,500 people opted in to their loyalty program.
