Upwork Upwork has many unethical and fraudulent freelancers on their website. San Francisco CA

I now have had two experiences with deceptive and dishonest freelancers that I connected with on Upwork. In addition, the testimonials that are included in freelancers profiles cannot be trusted since one freelancer wanted a signed, written agreement that I not be allowed to post a negative review of her performance. Furthermore, Upwork deletes posting of negative interactions between freelancers and clients. One freelancer wanted to get paid 50% of the contract upfront, before doing any work, and then asked me to sign an agreement that she could stop work at any time at her discretion, after being paid $12,500.00. 

Another freelancer that responded to help with advertising on Amazon, has since disappeared from the Upwork website, but not before he charged me to produce many Amazon Marketplace ads that performed terribly.

In my experience, many shady characters reside on Upwork and while I'm sure some are legitmate, I can say from direct experience that many are not, be aware!
