"Hey look, a starving family was just donated raw human flesh and a pile of shit! It's not healthy, and it's probably going to fuck up their immune systems and their bodies, but at the end of the day, it's food!"
Not all new content is good, not all new content is worth adding, and not all good content will help. Look at how many updates DarkRP has gotten, and the highest population I've seen is a flat 30. They're desperate, and clearly, new content doesn't seem to be helping as much as you and other little boys hoped.
