I've had a few emails from some outfit called Star of Service offering prospective jobs, however taking a look at their website, I'm a bit dubious. Does anyone know about them and whether they're legit?

They seem to be present in quite a few different countries around the world.

One of the things that raises alarm bells is their model seems to be that freelancers have to pay (via spending pre-purchased credits) to quote on a job. Plenty of freelancer sites charge some sort of commission of jobs, and that's fine, as money only changes hands when everyone gets something, and it's in the interests of everyone that jobs get completed satisfactorily.

Paying to bid on a job without any certainty whether you'll get it seems to be a bit of an unusual model, and not particularly freelancer friendly, as you have to purchase credits up front, then spend them whether or not you even get a job. I also wonder if there's an incentive for the site to encourage as many bids as possible on each job, as they get paid for each bid.

Does anyone have any experience with them, good, bad or otherwise?
