Having been a Buyer on this site and worked as a seller, I have to say that preference is shown to Buyers. High rates charged for work completed, advertising add ons which seem overly expensive, no prior vetting of any freelancers, no access to funds paid when refunded (you are given a credit instead of an actual refund)
Commission fees are in excess of 20% for sellers, poor customer service, charges to lodge a dispute, most processes including refunds being automated and often carried out in error with no recourse to issues being remedied...
Would not recommend.
