I don't have a problem myself. You should post your specifications on the browsers you are using. (I have no issues with up to date Chrome on both mobile and Windows)
I think it would be fair to have an option setting for users to either completely disregard blacklisted items in their feed, or continue to keep the blacklisted items in their feed but remove them manually. That way if someone reaaaallly wants to take a peak at their own will they still have the option to?
