Don't get me wrong, I'm not denying their veracity, I just think it's interesting.
I think overall my opinion is 'it's up to Twitter what's on Twitter, whatever' - but also that personally I like its 'this claim is disputed' etc. banners, but I think the outright removals that destroy the record, break news articles, etc. are a shame.
Couldn't the more egregious stuff just be more like HN's greyscale demotion and 'showdead'? '¡This tweet contains false information, appears designed to incite violence! '? Sort of like 'some viewers may find the following scenes distressing'.
