Aspire.io vs. Traackr

I used Aspire to find influencers for my fashion business and most of the influencers who signed up for my project were unreliable and did not fulfill their contract terms. For example, of 5 influencers I sent products to, only one completed the work that was agreed upon under the Terms. The others received a $195 product and disappeared, even though we signed a contract called Terms that is monitored by Aspire. The main downfall with Aspire is that it doesn't have a system in place to control this. For instance, they don't have a way for brands to leave a review for influencers and they don't block bad influencers (many just want free product) from applying for future projects. Aspire doesn't take responsibility for anything. What is the point of paying money to Aspire if they don't vet their influencers and control the quality of influencers who use their platform?
