If not then a well intended sham. The couple negative reviews here are consistent, slow engagement, little follow up, wrong skills. Likely an algorithm throws the multiple job post responses, as I have seen identical replies from different profiles. I think it's a bit shady on company side and the worker side as well, so your getting stuffed from both ends... not a good thing in this case.
Look at all the positive reviews here, do you notice anything...? Similarities. Coincidences... lots of animal and nature loving profile pics huh. I m sure it has worked for some, but not at the scale they suggest. It only has to work once for it to be legit, so yeah, its legit. You could sign up, you could find a good VA, you could not? But the smell test is starting to stink.
