I am so glad I found your article. Thank you for the honest review and all of the other resources as well. I too signed up for Contena, I didn’t quite understand what it was all about. I was told that it was closed and I had to wait for an opening. During this time I found out it’s a paid service, and decided not to proceed. Maybe a few weeks after that, I started getting several emails and texts per day telling me they need writers. The emails have continued for weeks. They say it’s closing soon, but I keep getting emails. Very spammy! Thanks again for this great article, even though it’s 2 years old, it’s full of useful advice.
