I've found SEOclerk to be overall just fine. Some workers are scammers, some are suboptimal (usually if they are offering English language articles without having great English skills), but most do the job they promised. Since it's one of the few major gig sites that mostly conform to the original $5 price range that Fiverr was founded on, if you lose a few bucks on a unsatisfying job it's an acceptable cost of doing business. I wish they had a faster way of showing that a gig is extinct, instead of one searching for a job only to see the 'red band of death' on the page that reveals the worker stopped offering it months or years ago. But it is a good alternative to Fiverr at least, and affordable in terms of cost or risk for small jobs.
