I am like the queen of free earning online..... basically because when I started I had NOOOOOOOO money at all (and I was very sceptical about online sites too). Years later and I still love my free sites. Here is a list of free sites that really do pay: https://ellenormurphy.com/free-sites-that-really-pay/
Have fun trying them out - I am sure you will find something interesting on the list!
I have really missed blogging since I stopped writing several months ago so I decided to start a new one. Big plans for this one.....
