Why is WordPress harming the revenue of this website?

It has always been my policy on this website to never charge people who want a case on this website. We do take donations for the site and do have ads as well. But the last two months has seen a decrease in ad revenue by almost 99 percent. From a few dollars a month to a few cents. When contacting customer service they say they will look into it and nothing is done. Views have not gone down. Why is this happening. Revenue earned from the ads help pay for the maintenance and hosting of the site. One has to wonder if they don’t like some of the minor political content or they view the content as violent. Or perhaps someone who may have a connection to a case on here has complained to wordpress itself and this in retalation for the complaint. I don’t know… All I know is the small amount of revenue that came from the ads helped out.
