While I expect a lot of people to not agree with what I am going to say, I believe this is much more linked to the political moment than to Twitter having a problem with "handling controversy". This just feels like an excuse to find a way to filter human communication, at this point.
Don't get me wrong, I'm a Brazilian and the latest years' politics headlines have been flooding Twitter around here too, but spurious political tweets tend to be much more boosted by people who don't agree with them -- they just feel that urge to answer it or create a hashtag against it -- than by people actually supporting said tweets.
