I second my sibling poster.
"It's easy for me to armchair quarterback these situations"
You have the self-awareness to recognise that you are "armchair quarterbacking", then you decide to... blame the guy for his problems, judge him negatively for speaking out, and go off on some airy tangent about the history of social security.
"This is a person who is susceptible to disasters, being forced into the street and can't manage the basics of living in the modern world."
What the hell? Basing your career on one online platform is not the best life decision, true. There's lots of freelancers who do more stupid things. Yes, this guy could have done things differently, but he doesn't deserve this kind of treatment.
If you are based in a tech hub or major city you can build a freelancing career with numerous digital agencies and other professional firms, and learn to sell yourself, manage client relationships, build a specialised skillset, etc. If you do that you also deal with a much better class of clients (have money, know what they want, don't screw you around). That is the exception, though.
The average freelancer hustles for generic projects and deals with the shittier kind of clients. This guy sounds like he is one of the more competent individuals in that category. Then he had a key relationship (with freelancer.com) turn sour, and as a result he's been absolutely shafted.
"If the reviewer posted this under his real name, then he should remove it. This review will kill his reputation" He's fighting back with the one weapon he has, which is going public with his experiences. He knows he is a taking a big risk with this. He is courageous.
On a final note: Jesus F'ing Christ where do you people come from. I've seen comments like this on similar stories. The temptation to victim blame (under the pretence of dispensing helpful advice) seems irresistible for many. I've been on the receiving end of this, so it gets my goat. An experience like this doesn't just hurt you materially and financially, it also smashes your self-confidence. But people are very selective in the things they are sympathetic towards. With other things, they respond with scorn and condescension.
