Hello Dear Hep
The Idea to cleanup P&H from those posters you do not like is always on our mind, and I think maybe you can "filter" words like exposed and those that annoy you besides blocking the posters one by one, we have already Hide content with following tags : [ x ] in your settings, maybe we can update this to count also "words" and not only tags, so anything that has the word "exposed" or other words that annoy you, can be auto hidden and you will never see them.
