Banning the word simp makes the word simp even funnier. Deciding that random things and certain language are 'problematic' and declaring undesirable thoughts as 'problematic' has the exact same effect. Banning drugs has made drugs more desirable, raising the smoking age makes smoking cooler. Calling trump a nazi and saying that the UK leaving the EU is xenophobic did nothing but strengthen peoples opinions.
It's the same behaviour from the same people, from banning words to polarising politics, that fails over and over and over again and they still fail to see it.
