None of the provided categories seem to fit the "Telegram" entity.

None of the given categories appear to fit with the name "Os Touros Negros". This name is likely associated with a sports team or a group related to the sport, which is not accounted for in the provided list.

None of the provided categories fit perfectly, but "Ethical Hacking & Cybersecurity" is the closest one, so I'll go with that.

None of the provided categories fit the title "FITI SHILL ARMY". However, given that "FITI" is likely associated with FTX, a cryptocurrency exchange, and "SHILL ARMY" is a common term for a community of enthusiastic followers, I would categorize this as: Cryptocurrency & Trading

None of the provided categories fit the title "DISTURBING".

None of the provided categories seem to directly fit with "Youth Bet Mart" as it may relate to a tech-related platform or service specifically catering to youth. Possible choices could be "Business & Finance" in a broader sense relating to services offered, but it is still a stretch.
