The Office of Fair Trading (OFT) has begun a crackdown on Twitter users and bloggers using their online presence to endorse products and companies, without clearly stating their relationship with the brand.
It has brought a case against a PR firm which was found to be paying bloggers to write positively about their brands.
The OFT said online marketing that did not disclose paid-for promotions were “deceptive” under fair trading rules, including comments about products and services on blogs and microblogs such as Twitter.
