After Mamihan Umarov gained fame, he retrained in a blogger and under the nickname “Anzor from Vienna” led the broadcast on his own YouTube channel. Over the past year, he gained a large audience and, in popularity, was equal to the other famous blogger Tumso Abdurahmanov living in Europe. Tumso Abdurakhmanov announced blood feud the speaker of the Chechen parliament Magomed Daudov for the insulting, according to Daudov, expressions to the father of Ramzan Kadyrov-Akhmad-Haji Kadyrov. On February 26, an unsuccessful attempt was made on Abdurahmanov.
The blog of Mamihan Umarova gained popularity, including due to the incontinence of his author.
Umarov did not so much receive and publicized information about what was happening in Chechnya as he personally criticized Kadyrov and did this in the most painful way for Chechens.
He switched to personalities, the mother of Kadyrov, parents and children, disseminated information about the orders that reign surrounded by the head of Chechnya and talked about humiliation, which Kadyrov’s associates were forced to endure from him.
Mamihan Umarov flaunted his permissiveness and more than once called the head of Chechnya and his security forces “to the arrow”, not hiding, on the contrary, emphasizing his place of residence in Austria.
