I does not matter if you are a buyer or a seller, Fiverr is the WORST place to be - stay away from it at all costs!
For sellers:
I was with Fiverr since the very beginning (where it was still cool) until my account was disabled for no reason a couple of weeks ago. Sellers beware, your account is at risk at any time, the support does not give a sh** about you and since this "company" sits somewhere in Isreal it's nearly impossible to take legal action (not that it would be worth the hassle anyway). To make things even better, all funds on your (for no reason) disabled account are frozen for 90 days and I highly doubt I will see any of that money ever again, even if the 90 days have passed. DO NOT SELL here. You can't make decent profits anyway, because Fiverr is swamped with sellers from 3rd world countries who can throw parties for their whole village once they earn five bucks (four that is after 20% fees). If you are in a western country, you do not want to compete against them, trust me. You're better off working minimum wage for Mc Donalds. They do at least not take 20% fees of your minimum wage, like Fiverr does.
For buyers:
We'll, there is really only one thing I have to say: You get what you pay for. If you like getting scamed by some third world individuals who will even insult you afterwards - this is the right place for you.
