This guy I hired off Fiverr - Olegakansonov, took 6 days to decide he didn't want to finish the development job, having trashed my site.
Maybe my own fault for trusting and going cheap... but still.
There is plenty of low quality and fishy people offering services on fiverr and the other freelancer platforms. You gotta proceed with caution. You're not alone who got burned... I had my share of experience with copywriters and translators.
Some were tying to sell me "spun" texts as original work... some translators used google translate and claimed to be native speakers
It takes time to find the right people on these platforms.
