Situation in 2016.
They blocked my client and blocked me. I did a lot of work, but they decided to suspend client (ugh...). Then they unblocked me. But me and this client we decided to move to another platform.
Then I did some jobs for other clients on UpWork. At some point with next client I faced situation of weird refund operations performed by UpWork support team. This is when contract was in Suspended status. So UpWork support first suspended my contract with this client, then perfromed some refund operations with my account, returning money to this client. And then I had lesser money, than I had when started this currently suspended contract (this is all when job was completed and client looked satisfied according to communicatons we had).
I do not uderstand what is rotten more - their support, their routines or their software (platfrom itself)...

Update from 2017.
They improved a lot, support is much better, more interesting projects available... I think they significantly improved a lot of things in this platform.
