One thing I really like about IOI and similar contests is that everyone gets a printed copy of the problem statements translated in their language.
While I understand that giving a printed copy to every contestant on codeforces would be hard, what stops us from having statements translated to our language?
I do understand english good enough, but sometimes I am unsure and it seems really unfair to me that english speakers have an advantage of this kind, so I propose that rated contests must have their statements translated to every language of participants!
You know what, registering on Codeforces should be done through an identity proof, so spammers can get banned for eternity.
