Funny story - there were some protests in my country some months ago. We're a semi-autocratic country on the verge of becoming a dictatorship. During the protests, the government used masked 'civilians,' or what you'd call 'titushkis,' to beat up activists at their home addresses or elsewhere in public. We were also getting calls from fake numbers on our personal numbers with threats.
A channel was created on Telegram by a government propaganda journalist, where they basically dox every activist, posting their addresses, phone numbers, and other private details, at times when these details are actively used for beating people to near death. That's the only content that Telegram channel produces.

I was one of the people whose details were posted on that channel. My phone number, home address, etc., were posted there, along with the private details of tens of others. I contacted Telegram support multiple times, we mass reported the channel - not once have I gotten an answer, and the entire channel is still up, for nearly 4 months.

So, hearing that he's arrested for lack of moderation? Good. I'm very happy. Hope he learns a lesson.

EDIT: Country is Georgia
