If you're suggesting that Donald Trump has some connection with the bans of controversial subreddits I think you're wrong, since the one big ban of fatpeoplehate, shitniggerssay and a few other controversial subreddits happened in 2015, a full year before Donald Trump's election.
But political subreddits didn't start seeing bans until 2016. Around the same time, the face of the major news subreddits drastically changed as well. I don't know if it was a result of the election, but the timing does seem to consider further consideration of motives.
And while they are less popular, there definitely are still subreddits dedicated to "legal aged women who look like very young teenagers wink wink" content, with rules that are entirely designed to argue the letter of the law so they don't get banned.
