These kinds of mass posts get flagged and removed pretty easily, that is, if you can even get past ghosting. My advice would be to post using images of what you want to say and include random hidden (yellow/white) text to have a greater chance of success. It takes a long time however, even automated before the cash starts rolling in, so if it starts to work for your niche, consider outsourcing the task and do something else to further expand your income streams
