I am a UK-based freelance programmer and have been getting jobs on Freelancer.com for the last six months.
Recently Freelancer.com stole $200 and £110 from my account within a span of a few days. They call it "Reversal of done milestone payment" but everybody else calls it THEFT.
They didn't even refund me the project fees until I complained to customer support. I have already filed complaints with Action Fraud UK and the UK Trading Standards office. I suggest to whoever has fallen victim to Freelancer.com and is resident in the UK to do the same.
I am in the process of withdrawing all my funds and moving to Upwork.
Conclusion: Freelancer.com is a SCAM and should be AVOIDED at all costs.
