I have probably spent a few K at fiverr mainly on marketing and can say some gigs are packed with value and others are a waste but have a few favorites. I haven't been happy with graphics work and haven't used any graphics that i paid for. Some of the site promotion is poor with many claiming traffic they don't have . The adult site promotion is rife with false claims. Plenty of hosted tubes trying to sell text links with add on's for price of a domain. The problem with fiver is the URL is hidden until you pay and hard to report problems with ease.
There is a lot of good and bad but you may need to sift though it all ask for more information.
