I've seen a lot of media activity on Twitter lately from Anton Gerashchenko @Gerashchenko7@Gerashchenko_en, especially within the international community. A lot of respectable people are retweeting his posts, so I decided to add some context.
The main thing to know is that he is a faithful soldier of odious Arsen Avakov. I won't do any revision of Arsen Avakov's wrongdoings; let's all admit that he is a чорт and keep on going. Anton Gerashchenko has never been arrested and prosecuted (as far as I remember).
