Overall I get value out of Upwork as a buyer, but a full 60% of the applicants I get are scam bait-and-switch accounts. I’ve figured out how to navigate it but it doesn’t surprise me that they’d be strict on their TOS.
This has been my experience as a client as well. Fell prey to a couple of "say we're doing the work but we ain't" devs that thankfully UpWork refunded so I'm glad to hear they're cracking down on scam accounts. Sad to hear that legit accounts are getting caught up in the process though.
