Hi all, we are a little agency and due to lack of time, we thought about using fiverr to outsource some work. I found a seller here on fiverr and i gave him work for about 10 projects. Now my client contacted me, that he got contacted by someone (the Fiverr guy) about the work. So the seller on fiverr contacts my clients. How would you react and what are the fiverr regulations? Thanks!
