The revelation of 
a marketing firm that claimed to be paying writers at high-profile online outlets to insert links to its client websites has dredged up old concerns about the ethical nature of some bloggers.
Gawker writer Hamilton Nolan shined the light on the company, which calls itself 43a, last week, posting a series of emails from what appears to be a company principal that offered up to $175 every time he linked to a site from one of their clients. In those notes, the 43a rep claimed to have worked with notable sites such as The Huffington Post and Business Insider, and had a client list that included Dell, Motorola Mobility and T-Mobile.
