1. Ads are out of control. I get that we can't avoid all of them, but if we choose to "hide all ads from this advertiser" because we're seeing one or more that are completely irrelevant to us, that choice should stick. Instead, the same ads keep showing up and clogging our feed. The buttons do NOTHING so why even bother offering them? 2. "Save" is broken, in that half the time it is no longer possible to save something to a collection. Please fix this!
