Blurb does NOT use Freelancer.com, Upwork, or any other job site to hire translators, editors, tutors, interpreters, data entry workers, or other roles. Anyone claiming to represent Blurb over these platforms is a scammer. They will ask you for a deposit and steal your money or hack into your bank account. The scammers may use the following names: Sonia Lamster, Joseph Madison, Reijnen, Joshua Susan, Clifton Geiger, Julia Hawk, Julia Hawkins, Gregory Wingerter, Kristine Clyde or Bob Rees.
If you're contacted by someone who claims to represent Blurb and offers you such work do not give them money. It's a scam. Please report them to the job site's support team immediately.
