I realise there's far more important things to fix on @twitter (say, banning nazis...) but I'd prefer not to see quote tweets of accounts I've blocked or muted. Mostly because I can't resist looking anyway.
Maybe there's a special secret code that makes this work...
tweetdeck is at least better at making it hard for me to look. But I do most twittering on my phone while travelling, and I end up accidentally annoying myself too much. Not that I want to avoid alternative views of course, but there's another time for that!
