does protect and does not protect,,,

I have this plugin on my website and I thought it worked well, like a sheet of glass over everything…and now i find out that audio files are showing up in my rss feed! so what is the point of trying to protect anything when audio is showing up on feed?

could you suggest a solution for me, as here was me protecting my content and now i find out it isnt on the bookmark feed.

please advise. thanks, in good faith.
