Basically: every work at home job on Craigslist is sketchy, if not a scam. Otherwise there would be no work-at-home jobs as they’d all be taken! Oftentimes the “job” consists of instructions on how to post work-at-home job offers! Yes I’m serious, you pay to be able to trick other people just as you were tricked.
The site you linked shows its true colors when you read their terms of service. Look at #7 – fees and pricing. You pay a monthly fee of almost $50 (maybe with tax it could be even more) in order to find these “opportunities” to be paid $25 per article (never ever trust the maximum, you’ll be lucky to get the minimum at best). You’d have to do two articles just to break even! It also shows its sketchiness when you go to leave the page, and it pops something up and asks you to stay and find more information about a special offer! One and one doesn’t add up here. If the job is really that awesome, why would they need to convince you to stay? The simple answer here is that the job is not that awesome at all. So technically the site is legit, but it’s clearly meant to get you to sign up for $50 a month and probably doesn’t offer even the two jobs you need to break even, let alone enough to seriously make money.
