One of the recent updates completely deleted the content I had in the bottom-of-every-post/bottom_of_every_post.txt file where you put what you want to appear at the bottom of every post. That content was replaced with links advertising his plugin and his website. So what he did was make it so the update deletes all your content and replaces whatever you have at the bottom of every post with spam links to his plugin and website, so he essentially used his plugin and the access it gave him to my site to spam his links on the bottom of every single one of my posts.
To say that this pisses me off is putting it mildly. If there's any way to report a plugin to WordPress I'm going to do it.
