Your article does not say that she was sentenced specifically FOR the smiley (and not i.e. for something she wrote online). On another hand, you are saying that sentence for a T-shirt is "common" (in my understanding it means that Estonia is very far, probably much farther than Belarus, from being a democracy). I can also reply to that with examples of people sentenced for tweets in EU or USA. This is also "common". And this discussion is actually getting nowhere, just shows that we have different biases.
