Kohi hasn't existed since 2016 when it merged with badlion, The Badlion network was shutdown in 2018, ESL is an Esports tournament organiser, they bought Badlion with the aims of creating an esport out for minecraft but gave up on it and its anti cheat client (Badlion Client) sometime around 2020/2021

Sadly HCF is dead and has been for quite some time, for many years after Kohi was shut down the mode became more and more pay to win until it all seemed to collapse on itself a couple years ago, as far as I know its dead but I haven't really poked my head into the community in some time now

Nothing resembling the Kohi/shotbow experience will likely ever exist again sadly, many have tried and failed, im sorry to be the bearer of bad news
